The old way of pressure relief valve testing could be summarized in one word: downtime. First, the plant went down, then valves were disassembled, and finally, the valves were transported offsite for testing. Time-consuming. Costly. High risk. But using the AccuTEST System, pressure relief valve testing comes to you, right where the valves actually operate. Time saver. Cheaper. Lower risk.

The AccuTEST System is a recognized leader in the valve service and repair industry. Why? Think fully automated one-touch testing for ease of use and repeatable results. It’s compact and portable to reduce the load of pressure relief valve technicians. Ongoing product enhancement based on technicians’ input. And we offer responsive technical support, anytime, directly from our engineers – not from a third-party representative.

Different to a safety valve test bench test an online safety valve test (or ISVT – In Situ Valve Test) is carried out on site with the safety valve remaining in its operational position and the plant remaining in operation. Whenever a safety valve “only” requires testing and no further maintenance or overhaul, a TESON online safety valve test is the most economic approach. Those who are new to the subject kindly refer to our Online Safety valve testing white paper.

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.

From the very fist moment employees need to be trained on how to use the equipment. And in case a trained expert leaves the company others will have to substitute him. Besides purchasing good equipment it is valuable to have a comprehensive documentation and training material, making you independent from external trainers, enabling self training. Further more suppliers should be able to offer professional training courses.

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..

With our FieldLab PSV/PRV Testing software and hardware, it is possible to conduct the test and record most of the information on testing a Pressure Safety Valve (PSV) or Proportional Relief Valve (PRV) directly on the calibrator. After the test is completed the data is then transferred electronically to a PC where a test report with graphs, customer data, tag data and other required information can be output and shared.

The unique PSV/PRV test mode captures the PSV crack and reseats pressure by logging pressure at 200 times per second. Most competitors" devices do not reliably capture the crack and reseat because the logging rate is too slow. The PSV/PRV mode also allows the user to select from standards such as ASME Boiler Code Section 8, simple crack tests or conditional crack tests where the allowable error may depend on the pressure of the PSV. The user can enter the pressure of the valve at the time of test and type in any other important information right on the FieldLab. Thus when the user returns to the office they can download all important information and create the certificates without a lot of extra effort.

In-situ testing of safety relief valves provides generally a good alternative to bench testing and ultimate tool for annual calibration of PSVs. Ventil offers since many years an electronic relief valve tester, PreVenTest. The PreVenTest is a world-wide used auxiliary lift assist device that is widely accepted and recommended by major relief valve manufactures. PreVenTest will test all brands of pressure relief valves.

The Ventil LTC PreVenTest is a lightweight, semi-auto online relief valve tester with a small and smooth stroking hydraulic pump. The PreVenTest advanced is a larger but fully automated device with computer controlled pulling force.  PreVenTest can be supplied as intrinsically safe version with ATEX and CSA certifications

PreVenTest comes with a set of accurate force / load transducers that measure the required pulling force to generate an initial lift of the valve. Further disc lift, acoustic are available and can be used for further analyses of valve performance and set pressure identification.

Reliable results can only be achieved when having accurate effective seat or pressure areas available. The PreVenTest Online Valve Test Software comes with a large database with accurate seat dimensions. The exact inlet operating pressure or line pressure must be known at time of the lift. PreVenTest features an additional connection to connect a pressure transducer. Typically achieved accuracy exceeds standard bench test results and are well within the tolerances of ASME VIII and PED

Aircraft alloy, lightweight but rugged fixture. The lift assist device is quickly installed at the valve and the time saving claw clamp feature makes connecting to the valve fast and efficient.

The Electronic Valve Tester, (EVT), is a digital computerized, hydraulic assisted device, designed to test and set safety/relief valves while in service. The EVT is portable and can be used under normal operating conditions without over pressuring the system.

Our Factory and National Board certified technicians, provide total safety/relief valve evaluation utilizing EVT technologies... at your convenience. The Electronic Valve Tester has been approved by the ASME for set point evaluation and or adjustment.

Safety valves are used in a variety of applications, including air/gas, vapor, steam and liquid service.  Flotech has been approved by the National Board of Boiler and Pressure Vessel Inspectors to perform safety and relief valve testing, repair and certification.

Our valve experts will focus on getting your valves tested, repaired and quickly set to the exact specifications.  We evaluate the repair condition of every valve and will recommend the right solution to manage your maintenance program.

Online safety valve testing is conducted by raising a load cell mounted on the stem of the safety valve, which in turn is raised. This helps in lifting the disk or seat. The valve is popped at the set pressure and the net result is calculated and hence there is no requirement to increase the operational pressure of the plant. Although an online safety relief valve testing is conducted during the plant operation (hot testing), online safety valve testing can be conducted during a shutdown (cold testing), which has a huge potential. Large safety valves which are hard to dismantle or remove off the line and require immense manpower, opt for this solution which is very cost effective.

Online test system for Safety Valves Pressure safety valves are installed on process equipment to release excess pressure due to faulty process opera- tions, external fires and other hazards. Or simply said; the safety valve serves to protect life and property. Failure of pressure safety valves to function prop- erly could result in the serious damage of vessels, exchangers, boilers, or other equipment. It is essential to maintain pressure safety valves and relief valves in good condition, periodic testing is one of the most important elements to ensure that the safety valves will pro- vide this important protection. In-Situ Testing Optionally available ATEX Explosion Proof IN-SITU TESTING Obviously, the most desirable type of test is one that subjects the pressure relief valve to the full operating conditions that it is to endure in practice. The PreVenTest system enables you to test your spring operated safety valves on site without interrupting the process operation. With this so called "hot testing" the safety valve stays on-line and no dismantling of the valve or plant shut-down is required. VENTIL, INNDVATDRS IN VALVE TESTING Ventil Test Equipment B.V.
