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.

For many years, ultrasound has been utilised by various vendors as an additional method to find the set point in cases the standard diagrams are hard to analyse. This can be the case when testing safety valves on liquid services.

Within an extensive benchmark test, METRUS in co operation with Sweden‘s biggest nuclear power station Ringhals AB investigated the approach to use ultrasound as an additional indication for the set point on liquid service safety valves. The result of 55 tests on different valves is that the „Ultrasound point“ is completely depending on the seat condition. This result perfectly first the fact that ultrasound will detect the start to leak point and not the set point (start to lift point).

Only on a new or freshly serviced valve, the set point will be close to the ultrasound point. Even tiniest soiling or improper maintenance will cause the ultrasound to severely „drift away“ from the true set point. Within a typical online safety valve testing scenario where a valve has not bee serviced for a year or more, it is not at all recommended to use ultrasound to identify the set point.

There are still two useful applications for ultrasound within online safety valve testing. A very simple but effective use is to compare the sound level of the valve before and after the test. Comparing those sound levels will indicate if after the test (disk lift) the valve is left in a similar condition to its previous untested state. This could be first information if the valve did properly reseat and seal after it has been lifted. White Paper – Online safety valve testing METRUS Valve Test Bench Exellence

Knowing why safety valves should be tested online and how this is done in theory, it is most helpful to get an idea of the every day questions you will have to deal with. It will enable you to imagine how online safety valve testing appears in real life.

Plant operators are often surprised when being asked by online testing engineers whether it is a problem to open a valve. Considering the definition of the set point to be the initial moment when the disk starts to lift the safety valve disk must lift to find that point in a test diagram. It very much depends on the test equipment how long and high the valve will open, but it definitely has to open. geöffnet wird.

To test a safety valve, it must be possible to lift the disk and measure the force when doing so. If a safety valve has a spindle, it is possible in 95% of all cases to test it online. Some valves might require a simple spindle modification. This depends on the valve and the adapter solution how to „connect“ the test rig. Valves that do not have a spindle at all can not be tested.

Valves installed on extremely dirty fluids like bituminous crude oil should not be tested unless they are equipped with a rupture disk to keep the seat clean. Dirt could prevent the disk from sealing properly and the valve will remain leaking after the test. It the maintenance departments decision whether to agree with slightly lifting a valve or not.

Safety valves installed in EEx areas require special equipment to operate the test rig. If such equipment is available, it is important to check the specific EEx certificate for the approved EEx class and EEx area. As of now and to our best knowledge, there is no online safety valve testing system available that has an EEx approval for the whole machine. The test rigs are approved but the power unit usually has to stay outside the EEx area or have to be protected with special temporary solutions.

A frequent question to be found in industry is „what is the highest set point and the largest nominal diameter you can test?“. According to the online testing formula of fig. 1 the set pressure is calculated from line pressure, seat area and test force. Those parameters interact. The more line pressure is to be found under the safety vales disk the less force is required to lift (test) it. A final statement can never be made as it depends on seat area, set point and line pressure, whether or not the force capacity of specific equipment will be strong enough to test a valve.

Some suppliers claim that their equipment can test „any“ safety valve. Technically speaking it means raising the line pressure will lead to a remaining test force small enough to be covered by the test equipments force capacity. As online safety valve testing should not affect the plant operation this statement is not very respectable. Usually the line pressure can not be changed significantly just to test a valve.

Thinking about the largest valves, small and medium valves are often forgotten. But those ½“ and 1“ valves built the majority of valves to be found in industry. It is a technical fact, that each measurement task requires suitable sensor ranges. Large valves require large forces and small valves usually small forces. The operational range of online safety valve test equipment is therefore not only defined by its strongest force capacity. It is a question how accurate it can deal with a variety of forces and pressures – small and large.

Online safety valve testing offers major cost saving potential. In most cases it is cheaper than workshop testing after comparing direct testing costs. This of course requires the test equipment to be efficient in handling and operation.

Safety valves need to be tested at various locations within a plant. It is common to move the test equipment a few times during a test day. Different valve types to be tested require retooling of the test rig. In every day life the equipment will be packed and unpacked several times and it will require adaptation to fit the test rig on the safety valve. Valves will be located on top of tall reactors and on difficult to reach places under or behind pipelines.

The test equipments performance is significantly defined by its mechanical performance – weight and flexibility. The time for unpacking and rigging up as well as for wiring all sensors etc. determines, how fast the individual valve test will be. And in many cases the safety valve requires adjustment. Depending on how long it takes to take the rig off the safety valve, testing and re-testing will be fast and efficient or time consuming.

Within a typical online safety valve test scenario, a valve might need to be adjusted. To adjust a valve, it requires to remove the rig (RR) adjust the valve (VA) and reinstall (RI) the rig before you can carry out the next test to see, if the adjustment was successful. This is done usually two times until a satisfying set pressure is adjusted.

The relation between handling and testing time in average test equipment is about 1/5. It becomes obvious that total test time and efficiency are significantly depending on the test rig performance – weight, portability and speed of set up / dismantling.

It may happen that safety valves stay open after the test. To make sure that such event does not affect the plant operation, a concept to remotely close the safety valve, using the test rig is absolutely necessary for safe online safety valve testing.

Testing safety valves online is not at all dangerous as long as the procedure is done properly and the system performs as it should. But there are rare scenarios in which a plant disturbance could appear, especially if a safety valve stays open or gets damaged.

Online safety valve test equipment today is either manually or electronically controlled. Electronic systems support the test process and monitor test limits, taking a lot of responsibility from the technician. TESON® e.g. automatically drives the complete lifting process, monitoring all sensor signals for pre calculated test limits. But electronic systems are sensitive to power black outs as well as to software malfunctions. To deal professionally with those, the online safety valve testing system must have an extensive safety system to guarantee the safety valve will never be blocked open or damaged – whatever might happen.

Manually controlled system are not sensitive to power black outs or system failures. They leave the full control over the test process to the technician. It is up to the technician to control the lifting force and whether or not to overload a valve. Especially with manually controlled system experience plays an important role as the safety issue is basically the human factor. Despite that even manually driven system must have some safety features to respond to hardware or hydraulic malfunction.

Considering the number of parameters to be considered and monitored during an online safety valve test, digital systems are definitely superior as the chance of malfunction and power black outs is considerably small if the systems are well designed and extensively tested. Even after intensive training and years experience it is barely possible for a technician to compete with the reliability and response time of a digital system. Considering the background of online safety valve testing it is a derived requirement of the system to be safely and correctly operated with minimum skill and experience.

When thinking of a first time investment, it is very often the purchase price that plays an important role. But if you consider the cost saving potential of online safety valve testing or the profit you could make with a service, it becomes obvious that there is more to be considered to get a real view on the cost of ownership.

Support from your supplier will be crucial for your business. If you are facing time sensitive testing sessions and your equipment gets damaged or you come across complex questions, delays of operations or loosing your customer to the competition can cause severe loss of profit. The system vendor should be able to minimize downtimes with an intelligent support strategy. This includes 24 h availability of technical support, access to most spare parts in local markets and availability of rental equipment to substitute yours during service and repair. The more a supplier is focused on the online safety valve testing business, the better resources he will offer to support your every day work.

Like all measuring equipment, online safety valve testing systems require calibration. Sensors and measuring electronic need calibration (typically every 2-3 years) to harmonize with ISO quality standards. Suppliers must be able to either offer you a calibration service or advice you where to get such service. To minimize transportation costs, the parts and modules that need calibration should be easy to isolate for shipping.

The variety of valves to be found in industry is huge. It is not at all practical to own every type of special equipment that might be required one day to test special applications. Your investment will be significantly lower if you can own core components that cover the majority of your every day online testing needs. Your supplier should offer you special extension for rent to cover the remaining applications once they are required.

We hope this white paper could draw a picture what online safety valve testing is about. If you have any further related question, please feel free to contact METRUS at any time. It will be our pleasure to support and consult you..

WITT is a manufacturer of Pressure relief valvesor Safety relief valves for technical gases. They are designed to protect against overpressure by discharging pressurized gases and vapors from pipelines, pressure vessels and plant components. Safety relief valves (SRV) are often the last line of defense against explosion – and such an explosion could be fatal. Other common names for safety relief valves are pressure relief valve (PRV), safety valve, pressure safety valve, overpressure valve, relief valve or blow-off valve.

WITT safety valves are very precise. They are individually preset to open at a predetermined pressure within the range 0.07 to 652 Psi. Their small size and orientation-independent installation allow a wide range of connection options. WITT relief valves also stand out due to their high blow-off flow rates of up to 970m³/h. They can be used within a temperature range of -76° F to +518°F and even with very low pressures.

For maximum safety, WITT undertakes 100 % testing of each safety relief valve before it is delivered. In addition, WITT offers individual testing of eachsafety valveby the TÜV, with their certificate as proof of the correct set pressure.

WITTsafety relief valvesare direct-acting, spring-loaded valves. When the preset opening pressure is reached, a spring-loaded element in the valve gives way and opens, and the pressure is relieved. Once the pressures are equalized, the valve closes automatically and can be reactivated any time the pressure rises again. Depending on the application and the nature of the gas, the safety relief valvescan either discharge to atmosphere, or via a connected blow-off line. The opening pressure of the safety valves is preset by WITT at the factory according to the customer’s requirements.

Safety relief valvesare used in numerous industries and industrial applications where, for example, gases pass through pipelines or where special process vessels have to be filled with gas at a certain pressure.

For most industrial applications using technical gases, brass is usually the standard material of construction of thesafety relief valvebody/housing. For the use of pressure relief valves with aggressive and corrosive gases, the housings are made of high-quality stainless steel (1.4541/AISI 321, 1.4404/AISI 316L, 1.4305/AISI 303 or 1.4571/AISI 316Ti). The use of aluminium as a housing material is also possible.

Depending on the type of gas used and individual customer requirements, various sealing materials and elastomers are available to ensure the safety of your systems under even the most difficult conditions.

WITT pressure relief valves are available with different connections. In addition to the standard versions with the usual internal or external threads, special versions with KF or CF flanges, VCR or UNF threads can also be ordered. Special adapters for connecting the safety relief valve to a blow-off line are also available.

The safety valve checkout platform is a device that simulates the working environment of the safety valve offline and makes the internal pressure rise to the safety valve lift.

The test pressure can be checked to check the starting pressure (also called opening pressure, setting pressure) of the safety valve. Suitable for performance testing of fixed pressure, backseat pressure and tightness of direct loading and pilot safety valves.

These valves do not fail very often. Normally the problem is with the ignitor not drawing enough amperage to open the valve. Even if the ignitor is glowing orange it is likely still the cause of the burner not igniting. Technicians refer to this as a "weak" igniter.

Dual gas safety valve assembly. The gas oven safety valve works with the oven igniter to provide gas to the burner. If the safety valve fails, the oven won’t heat. Since safety valves rarely fail, be sure to check more commonly defective parts before replacing the safety valve.

With an ever-increasing focus on reducing maintenance expenditure, there is a need for safety critical equipment to function reliably. With preventative maintenance on pressure safety valves (PSVs) being one of the more significant integrity costs, increasing efficiencies in this area is important, with potential for time savings and performance improvement.

The Pressure Safety Valve Manager digital tool is client-accessible and contains all the information used in the RBI, including the (pre-pop) results. Detailed tabs contain the PSV performance history for the asset(s). The tool may also communicate with the operator’s computerized maintenance management system (CMMS) to accurately relay, not only the performance history of each PSV, but also information useful for maintenance planning, such as shutdown requirements, online testing capabilities etc.

While it"s possible to manually shut off your natural gas, the following specialized valves are available that can automatically shut off your service in case of an emergency:

Earthquake natural gas shut-off valve (also known as a seismic natural gas shut-off valve) automatically shuts off your natural gas service when an earthquake of a sufficient magnitude occurs at your home.

An excess-flow valve (EFV) automatically closes and restricts the flow of natural gas in the event an underground pipe is damaged or if there is a significant increase in the flow of natural gas to the meter.

If you want to have an earthquake natural gas shut-off installed, or are required to have one by your insurance company or the local Department of Building and Safety, the valve must be installed on your house line.

If installation requires natural gas service closure, you"ll need to contact us to shut off the service and restore service when installation is completed. Natural gas service shut off and restoration of service orders can be scheduled by contacting us at 1-800-427-2200.

Under the regulations of the California Public Utilities Commission (CPUC), General Order 112-E, only SoCalGas® or its certified contractors are authorized to operate the natural gas service shut-off valve.

When you hire a qualified professional to install your earthquake valve, you"ll need to make sure that the valve is installed on your house line, not on SoCalGas" facilities. SoCalGas" facilities include all of the pipe fittings installed and maintained by SoCalGas, up to and including the last elbow or tee connecting to your house line. See the diagram below for to see where your house line starts.

All unauthorized valve installations found on SoCalGas" facilities will be removed. In addition, earthquake valves are not permitted in utility curb meter vaults.

If an earthquake or other significant event causes your earthquake shut-off or excess-flow valve to close, you can follow the manufacturer"s instructions for resetting the valve so that natural gas flows again. However, we recommend that you contact a qualified professional or SoCalGas to reset the valve, and to perform a safety check of your natural gas appliances before they are placed back in operation to verify that no natural gas leaks exist, and to re-light your pilot lights.

Remember that following a major emergency it may take many days or even weeks before someone can come to your location. (SoCalGas charges a fee to reset valves and re-light pilot lights when your earthquake shut-off valve has closed due to a non-earthquake occurrence.)

Price: The cost of the valve is going to vary based on the type and size of the valve, as well as the installation requirements and the company installing it.

Choosing a valve: In order to choose the right valve size and manufacturer, contact your local Department of Building and Safety to find out their earthquake valve requirements.

Where to buy a valve: You can purchase an earthquake valve at supply retailers, licensed plumbing contractors, or directly from the valve manufacturer.

Using a contractor: You can hire a qualified professional to install the earthquake or excess-flow valve on your house line. SoCalGas will not install a valve for you.

Effective February 10, 2002, California Public Utility Commission (CPUC) Decision 01-11-068 prohibits installation of an earthquake valve on SoCalGas" facilities. In addition, SoCalGas no longer installs earthquake shut-off valves for its customers, and does not allow any customer owned equipment, including excess-flow valves, be installed on SoCalGas" facilities.

If you have an earthquake valve that was installed by SoCalGas or one of its authorized contractors on or before the February 10, 2002 cutoff date, that is located on SoCalGas" facilities, with proper documentation your installation may be allowed to remain in place. Authorized contractors are those who participated in SoCalGas" earthquake program and were trained by SoCalGas to work on their facilities.

Additional information regarding earthquake valves and natural gas service restoration after a valve activates can be found in Tariff Book, Rule 10, Section G, "Earthquake Valve Service."

An Excess Flow Valve, or EFV, is a safety device installed on natural gas distribution pipelines to automatically close and restrict the flow of natural gas in the event an underground pipe is damaged or if there is a significant increase in the flow of natural gas to the meter. These conditions are typically caused by digging or construction but can also be caused by damage to your natural gas meter by a vehicle impact.

EFV can reduce the risk of explosions, fires, and personal injury because they close or restrict any unplanned or excessive natural gas flow. Installation of an EFV will not protect a customer from household appliance malfunctions, small punctures in underground pipelines, and pipeline damage from earthquakes or flooding. It is

important to understand that an EFV does not shut off the flow of natural gas completely. Some leakage may still occur resulting in a hazardous condition.

An EFV is installed on the service pipeline that runs underground between the natural gas main (usually located in or near the street, alley or easement) and the SoCalGas® meter on the customer’s property).

The best way to prevent damage to a natural gas pipeline due to digging is to call 811, the Underground Service Alert program, at least two working days before digging. Underground Service Alert will coordinate with SoCalGas to mark the locations of buried utility-owned lines - absolutely FREE.

If you are interested in having an EFV installed on the service pipeline serving you[1], please call SoCalGas at 1-800-427-2200. SoCalGas will first check to see if your service already has an EFV installed and, if not, an estimate to install the EFV will be provided. The cost to install an EFV can vary widely depending on site specific conditions and can range from $2,500 to $5,000 or more.

If you decide to have an EFV installed, we will coordinate with you to schedule the installation (note that it is possible that natural gas service will be interrupted to install the EFV). The construction crew will dig around the natural gas line in order to install the EFV and when the job is complete natural gas service will be restored (if it was shut off). If paving or concrete needs repair that work will be scheduled at a later date.
