We understand that you face numerous regulations regarding the ongoing certification of pressure relief valves. These regulations and timeframes can vary from state to state, and from OSHA 1910.119 process safety requirements, to insurance carrier requirements, even to local jurisdictional requirements.
Maintaining a documented safety and reliability program that complies with the respective regulations and includes easy access to the required documentation — all while trying to reduce overall operating cost — can be very challenging.
Allied Valve has a solution and the support!
You don’t need to have a plant or unit outage to become compliant again. And you don’t have to spend extra time and money to remove your flanged valves from service to have them recertified, and then reinstall them.
Using our GE EVT Pro 2.0 X (the only 100% intrinsically safe Electronic Valve Tester in the United States), factory certified technicians can test your pressure relief valves while your system is running. This saves you time and money in the certification process.
All test data can be loaded into ValvKeep, our web-based valve management system. As a customer, you’ll have a private account where you can view or print valve test records, repair records, and repair history. You can customize ValvKeep so you can see exactly the information you need. You can even edit the fields to track your valves’ location and status, as well as upcoming service events. Valve lists can even be exported to an Excel spreadsheet, so you can keep track of valves that need testing, service, and so on.
It’s a simple and powerful solution. Here are the requirements to use the EVT Pro 2.0 X:
- Certification within the applicable code requires that the gauges (or Pressure Measuring Devices) used in the valve testing process must be within ±0.25% tolerance of the PMD’s full pressure reading.
- The PMD must be calibrated to a nationally recognized standard within a calibration cycle acceptable to the company performing the testing.
- In short, if the owner / operator’s PMDs are used, they must be accurate to ±0.25%, calibrated and documented within an acceptable time frame, and verified by the valve testing company.
- The other option is that the owner / operator can provide a block and bleed type gauge tap relatively close to the valves to be tested. That way, we can provide our PMDs, which are calibrated and documented to a nationally recognized standard and, generally, a 0.1% tolerance.
- The optimum inlet pressure at the valve inlet for testing purposes is 70-85% of the tag pressure on the valve. Greater pressure may result in the valve going into full lift (popping). Less pressure will result in a decline in test accuracy (50% is the absolute minimum inlet pressure required).
Once these three conditions have been established, the technician will remove the valve cap, set up the test equipment, hydraulically lift the valve (partially), and let the computer record and process the data to establish the opening pressure of the valve, as well as pass or fail testing. We’ll even tag the valve with a pass or fail tag.
