testing gas safety valve factory

Trouble turning on your gas stove? If your igniter is glowing but there is no flame, then one of two components in your range are at fault. These components are the “safety valve” and the igniter itself.

Take a clamp-on type ammeter, and attach it to the circuit to determine whether the igniter is working efficiently enough to open the safety valve. Clamp your meter onto the wire that either goes to the bake burner igniter or the bake burner safety valve. Turn on the bake function, and see what current is drawn. Typically your meter will show 2.8 – 3.0 amps for a normal current draw for a working igniter. If your meter is showing 2.7 or lower then you can assume that the igniter is not drawing enough current to actually ignite the flame, and therefore it won’t open the oven safety valve to allow the gas to enter the burner chamber. If this happens, it’s time to replace the oven burner igniter.

To test the oven safety valve, measure between the two terminals, on the valve and look for continuity. The resistance here is low, but you should be able to detect 1 to 1.5 ohms. If your model uses a dual valve, one for the broil burner and one for the bake burner, then you will have two bi-metals and again you can test them for continuity using a multimeter. They also should be very low resistance and those would indicate that they"re normal working oven safety valves.

If after performing these tests, you"ve determined that you need to replace your gas range"s oven safety valves, oven igniter, burn igniter, or safety valves? Take a look at our large selection of oven parts.

Media flow hydraulic processes and procedures are heavily dependent upon quality valves. Failure in a piping system from faulty valves can incur considerable and costly damage. In some cases, these failures may risk catastrophic property damage or injury and death to workers.

Because of the critical role valves have in complex and intricate processes, proper inspecting and routine testing should be part of a risk mitigation plan. Today, we’ll go over the kinds of valves, industry standards, and testing you might encounter.

While the function of a valve is relatively simple, the designs are diverse and sometimes complex. Below is a list of valves you may already be familiar with along with their applications.Butterfly Valve – A quarter-turn valve used to control the flow of liquid, gas, or particulate matter. It is used in treatment plants, food industry, ship industry, petrochemical plants, fire extinguisher systems, paper manufacturing, and many more applications.

Ball Valve – A shutoff valve with a rotary ball controls flow and pressure control in gas distribution systems as well as pressure reduction in connection with gas storage. It is used in applications involving corrosive fluids, slurries, or normal liquid and gases. Applications are found in the oil and natural gas industry, manufacturing sectors, chemical storage, some residential uses, etc.

Globe Valve – A linear motion valve used to start, stop, and regulate flow. It may be used for isolation and throttling. Applications include cooling water systems, fuel oil systems, feedwater or chemical feed systems, turbine lube oil, boiler, and main steam vents or drains.

Check Valve – A one-way, non-return valve where the flow runs freely in a single direction and works to prevent backflow. It is used in pumps, fluid systems (for chemical and power plants), and more.

Needle Valve – A plunger valve with a small opening (or port) that has a needle-shaped plunger that allows precise regulation of flow. It’s ideal for systems with lighter and less viscous media with low flow rates or systems with small channels and pipes. This valve regulates gas or water through an appliance or system.

Gate Valve – A sluice valve that is multi-turn and works by inserting a rectangular gate or wedge in the path of a flowing media. A threaded stem connects the actuator (such as a handwheel or motor) to the gate’s stem. It is found in industrial applications such as pharmaceuticals, manufacturing, automotive, oil and gas industry, or marine. It’s also useful in underground applications and is ideal for vertically-oriented setups (as it is space-saving).

Pinch Valve – A full bore or fully ported valve that “pinches” to obstruct the flow of fluids. It’s used for liquid, solid, and slurry applications. It’s ideal for isolating or regulating media that is abrasive, corrosive, and fibrous.

Plug Valve – A quarter-turn rotary motion valve where a tapered or cylindrical plug is used to start and stop the flow of media. Applications include natural gas piping systems, oil piping systems, coal slurries, mineral ores, mud, sewage, or vacuum to high-pressure applications.

Pressure Relief Valve – A safety relief valve designed to open at a preset pressure level and discharge fluid until an acceptable level of pressure is reached. It is necessary for applications where pressure levels are critical (such as oil and gas, petrochemical, or power generation using steam, air, gas, or liquid). Applications include firefighting, high-rise building systems, water towers or tanks, drinking water systems, or multi-phase applications in refinery and chemical processing systems.

Smooth and safe operations of industrial processes and equipment rely on control valves that perform with precision. The quality of production is optimal when valves most effectively regulate process variables such as temperature, pressure, and flow.

Testing valves to monitor performance promotes both product quality and (most importantly) safety. Valve failure has been to blame for several plant or refinery explosions. We follow set protocols and industry standards to ensure safety.

Globally-sourced products are on the rise, yet domestic manufacturing has scaled back, so every part of the valve supply chain sees a need for more testing.

Set standards achieve two aims: puts in place criteria that the valve is expected to meet or exceed and establishes testing procedures. This ensures the integrity of the valves and that the valve is fit to do its job within a process. Reliability and longevity are vital to these operations and testing allows us to make adjustments and repairs where necessary.

For the oil and gas industry standards, there is the American Petroleum Institute, and for general applications, there is the American National Standards Association. Below are some specific testing procedures found in various industries.

The API 598 covers the testing criteria of various types of valves (soft & metal seated). This valve inspection covers, examination, pressure, and leakage rates for metal-seated and resilient seated valves (including a butterfly valve test). In order for a valve to pass the test, there must be zero leakage

This standard applies to the testing and performance evaluation of the straightway, soft-seated quarter-turn valves when the valves are exposed to fire conditions.

This international standard testing applies to ball valves, check valves, plug valves, and API6D design pipeline check/gate valves. It specifies those requirements and provides recommendations for the design, manufacturing, testing, and documentation of these valves. This test is associated with Petroleum and Natural Gas Industries-Pipeline Transportation Systems-Pipeline Valves

This testing is for valves, gauges, and other safety fittings involved with boilers (including its piping installations). Specifications apply to the associated valves, mountings, and fittings.

To give you an idea of what testing is applied to determine the efficacy and the health of valves in industrial applications, we’ll go over those evaluation measures.

The valve is checked for leaks by having it partially open and subject to hydrostatic pressure at 50% higher than the rated working pressure. A specified amount of pressure is applied during this test. There are also specific water temperatures in effect (41°F to 122°F). In order to pass the test, there must not be any leaking from the valve. When valve material includes stainless steel, chloride ion content must be less than 100 ppm.

This test has the valve completely closed with the inlet subject to the hydrostatic pressure with the valve body filled with the testing fluid at a certain temperature.

The outlet side of the valve is monitored for any leaks. Pressure cannot be lower than the 110% maximum allowable pressure at 100 °F. The duration of applied pressure is usually one minute. For the valve to pass the test, it cannot leak from the stem and packing. A minimal amount of leakage from the sealing surface of the disc and seat is acceptable.

For this test, the valve is fully opened while the valve ends are closed. Pressure cannot be lower than the 110% maximum allowable pressure at 100 °F.

The testing duration lasts 15 seconds for a valve that’s less than 2 inches and for valves more than 2 inches, it lasts 60 seconds. During this process, the packing gland is closely inspected while it is under the backseat test pressure. It passes if there are no leaks from the valve or from the packing gland.

Industry standards and testing procedures in place offer the necessary guidance to maintain safe and optimally-performing operations. For each valve in your process, you should have routine testing as part of your standard operating procedure.

When it comes to understanding pressure relief valve testing requirements, there’s a lot of information out there, but not all of it seems conclusive. If you’re new to pressure relief valves or are getting started in a new industry, it can be tough to decipher what testing requirements your facility needs to meet.

While we can’t provide the specific testing requirements for every industry, we can offer a few general testing requirements, and point you in the right direction to find the information you need for your facility’s unique testing requirements:

It’s good to keep in mind that every industry and region has unique pressure relief valve testing requirements. Your facility may be required to just bench test pressure relief valves every five years, or you may have to test valves every year, but bench test and repair valves every three to five years. There is a large variance in the testing requirements for pressure relief and safety valves depending on your industry and your region. That said, there are a few general testing requirements we can look at to start with.

The National Board Inspection Code, created by the National Board of Boiler and Pressure Valve Inspectors, makes the following recommendations on the frequency of testing for safety and pressure relief valves, depending on the temperature, psi, and function of your boiler:

High-pressure steam boilers greater than 400 psi should be pressure tested to verify nameplate set pressure every three years, or as determined by operating experience as verified by testing history.

It’s important to remember that these are general pressure valve testing recommendations. For specific requirements, you’ll have to verify your unique jurisdictional and industry code requirements. See the resources below for more information.

The National Board Inspection Code is an industry-recognized name offering quality information on pressure relief valve testing requirements. Here, you’ll find a wealth of information and testing best practices.

The ASME is another organization setting pressure relief valve testing requirements, and offering the necessary training engineers need to test and understand the testing procedures for pressure relief valves. In addition to testing requirements and standards, the ASME offers a variety of online courses on pressure relief valves, from fabrication and proper installation to inspection and repair.

For specific testing standards, it’s best to check with your industry and your regional jurisdiction. Pressure relief valve testing requirements can vary by state or region and are most often industry-specific. Check your industry’s standards, and check local code requirements to ensure your facility is adhering to the most relevant pressure relief valve testing requirements.

When you’re looking for the pressure relief valve testing requirements relevant to your facility, it’s important to understand the different testing methods that are available to you. It’s likely that regardless of your industry if you have safety and pressure relief valves in use at your facility, you’ll have to bench test those valves at least every five years.

In addition to those bench tests, though, you’ll also have to perform manual or on-site pressure relief valve testing. Here’s a quick look at the three most common pressure relief valve testing methods you’ll see when researching pressure relief valve testing requirements:

The most commonly mandated form of pressure relief valve testing, bench testing is unique in that it requires you completely shut down your facility’s system and remove all pressure relief valves. The valves are then transported to a lab where they are tested and repaired as necessary. Tested valves are then re-installed in your system.

Bench testing is the most involved method of pressure relief valve testing, but as this is how valves are tested when they’re manufactured, the industry considers this to be the most thorough testing method.

Inline testing is another accurate pressure relief valve testing method that doesn’t require the removal of valves or facility downtime. With inline safety relief valve testing equipment, a trained technician can test valves in the system to calculate the real setpoint of a valve in the system.

While inline testing cannot take the place of mandated bench testing, it is a more efficient form of testing for other regular testing requirements. Inline pressure relief valve testing is the ideal choice for any required testing that does not have to be bench testing, as it eliminates the need for downtime while still providing exceptionally accurate results.

Some pressure relief valve testing requirements will call for regular manual testing for freedom of operation. This is a basic test that can be done on-site. To complete an operated-in-place test, the test lever on the valve is manually activated. This test functions to ensure that the valve can open and shut tightly, but it does not verify at what pressure the valve opens and shuts. This is a test that may be required quarterly or bi-annually, to ensure the most basic functionality of safety relief valves.

Pressure relief valve testing is necessary for any facility with safety relief and pressure relief valves. For more information about the equipment you need for pressure relief valve testing, the profitability of certain testing methods, and more, head to the AccuTEST blog. There, you’ll find a variety of resources on everything from implementing inline safety relief valve testing to minimizing plant downtime.

Because of their importance, checking or calibrating valves is critical, but creating a consistent test result is difficult, as two technicians may interpret the analog test gauge differently.

Companies use pressure relief or safety valves to protect equipment from pressure spikes. Because of their importance, checking or calibrating these valves is critical, but creating a consistent test result is difficult, as two technicians may interpret the analog test gauge differently.

Crystal has a solution with its XP2i Digital Pressure Gauge. The XP2i features a special PSV mode designed to test pressure safety and relief valves. Once the valve opens, the XP2i detects the pressure drop and displays the maximum pressure that the gauge ever reached before the drop. This value remains on the display until the technician clears it. Rather than two technicians possibly reporting different values when the analog gauge spikes, with the XP2i both technicians would write the same value, even to a thousandth of a psi.

The XP2i Digital Pressure Gauge features three accuracy levels to choose from, 0.1% of reading, 0.05% of full scale, or 0.02% of full scale. They are available in ranges from vacuum to 15,000 psi and are fully temperature compensated from –10 to 50 C. All versions are ATEX, IECEx, and CSA intrinsically safe, making them ideal for the oil & gas industry and others requiring intrinsic safety. An optional datalogging upgrade allows the XP2i to collect and store up to 32,000 data points and easily download the results to a spreadsheet or protected pdf file.

A pressure safety valve (PSV) is a failsafe used to protect people, property and processes from process over pressure. Designed to open immediately to relieve pressure when system pressure reaches a certain level, known as the set pressure, they then close back up to prevent the further release of fluid or gas once normal conditions have been restored. PSVs are essential to the protection of lives and equipment, particularly in the oil & gas, power generation, water/wastewater, aerospace/aviation, steel manufacturing, and chemical/plastics industries. They are purely mechanical so they’re capable of operating at all times and are considered the last resort in preventing catastrophic failure in systems under over pressure conditions.

As the final link in the safety chain, safety valves need frequent testing to ensure they’re in good operating condition and functioning properly. The mechanical parts can stick closed, wear over time and exposure to contaminants and corrosion can affect the resealing or closing of the valve seat after release that could result in a leak. Depending on the industry in which they’re being used, it’s recommended that they’re tested at least every 1-3 years, or more frequently depending on previous inspection history.

PSVs should be tested at their operating pressures and temperatures. A test can be performed "in-situ," while the valve is still in service, but the set pressure is often challenging to create in the field so they’re more commonly removed from the system entirely and taken into a lab/test center for bench testing.

During a conventional PSV test, a technician carefully supplies rising pressure to the valve until it pops (or "cracks"), compares that pressure to the set pressure, and records the results. The goal is to ensure the valve will open and perform its function at the desired set pressure and that the reseal event happens at the desired lower pressure.

To get started you’ll need to connect your PSV, a pressure reference gauge, and an external pressure source. Be sure to follow ASME Section VIII standards for the type of valve being tested.

Step 1: Before you start testing, determine the set pressure of the PSV. Every PSV has a set pressure engraved on the tag riveted onto the body, which is the reading at which the valve should pop open to quickly release pressure. Be sure that the gauge you’re using has the correct measuring range to accommodate the set pressure.

Step 3: Slowly decrease the flow of pressure and record the reseating pressure value, or the pressure point at which the valve closes. If the volume of your pressure source is too low, this will happen instantly and the lower pressure may be difficult to record.

Though the basic PSV testing procedure is relatively easy to perform, results are certified by a technician based on simple observation with little hard data to back it up, and certificates are signed and issued with little to no traceability other than the technician’s word. Even two highly trained technicians observing the same test may record different results, which highlights the inherent potential for human error in this type of standard PSV test.

Accurate testing of PSVs requires extremely precise measurement of the cracking pressure when the valve lifts, and the exact moment when the valve reseats. The FieldLab’s unique PSV/PRV test mode detects the PSV crack pressure and reseat pressure by logging pressure at 200 times per second - far quicker than the logging rate on other devices. It allows the technician to conduct the test and record all of the data directly on the gauge, and then transfer it electronically to a PC where a test report with graphs, customer data, tag data and other required information can be output and shared. It can also perform a leak test and make a judgement of pass or fail based on the ASME standard.

Though the terms Pressure Relief Valve (PRV) and Pressure Safety Valve (PSV) are often used interchangeably, it"s important to understand that PRVs are designed to control pressure in a system. They open gradually in proportion to increasing pressure and are mainly used in fluid or compressed air systems. A PSV is strictly a safety mechanism with no attempt to control the pressure. PSVs open immediately and fully with a "pop action" when the set pressure is reached.

The Pressure Safety Valve Inspection article provides you information about inspection of pressure safety valve and pressure safety valve test in manufacturing shop as well as in operational plants.

Your pressure safety valve is a direct spring-loaded pressure-relief valve that is opened by the static pressure upstream of the valve and characterized by rapid opening or pop action.

Your construction code for pressure safety valve is API Standard 526 and covers the minimum requirements for design, materials, fabrication, inspection, testing, and commissioning.

These are:API Recommended Practice 520 for Sizing and SelectionAPI Recommended practice 521 Guideline for Pressure Relieving and Depressing SystemsAPI Recommended Practice 527 Seat Tightness of Pressure Relief Valves

For example if there is pressure vessel need to be installed in the state of Minnesota then the pressure vessel nameplate shall be U stamped and pressure vessel safety valve shall be UV stamped.

National Board Inspection Code (NBIC) have own certification scheme for pressure safety valves and using NB symbol. The NBIC code book for this certification is NB 18.

There are some other standards and codes which are used in pressure safety valve such as:ASME PTC 25 for pressure relief devices which majorly is used for assessment of testing facility and apparatus for safety valvesBS EN ISO 4126-1, 4126-2 and 4126-3 which is construction standard similar to API STD 526.

This API RP 527 might be used in conjunction of API RP 576 as testing procedure for seat tightness testing of pressure safety valve for periodical servicing and inspection.

These are only important points or summery of points for pressure safety valve in-service inspection and should not be assumed as pressure safety valve inspection procedure.

Your pressure relief valves (PRVs) are some of the most important pieces of equipment in your plant. They are what protects your systems from overpressure events that can damage your systems and, in some cases, have catastrophic consequences.

One of the most common questions we get is about relief valve testing frequency. There is no single answer that’s right for every valve or application. It depends on the service conditions, valve condition, and level of performance desired.

Effort should be made to conduct inspections and testing of pressure relieving devices at the time they become due in accordance with the schedule previously established, assuming that the equipment has been in continuous operation, interrupted only by the normal shutdown.

The required testing frequency depends on the service. For example, a valve used in a corrosive or fouling service needs to be tested more often than the same valve used in a noncorrosive, nonfouling service. Other conditions that call for shorter testing intervals include:

It’s also important to look at the valve testing history over time. If the valve consistently passes the test, then it can be tested less often. If the results are inconsistent, then the valve should be tested more often. For new processes, especially those where the service conditions (corrosion, fouling, etc.) can’t be accurately predicted, the initial inspection should be performed “as soon as practical after operations begin to establish a safe and suitable testing interval.”
