PSV test bench is used to test the sealing performance of the safety valve, the leakage test of the disc and seat interface seal; the fine-tuning leak test; the function test and the working pressure adjustment. Comply with relevant national standards and test all types of safety valves up to DN600mm.
Meets test standards: API 598; API 527; DIN EN 12266; ISO 5208; ASME B 16.5; ASTME 1003-05; GOST 5762-2002; National Standard 9544-2005.
Connection method: flange, thread.
Test object: safety relief valve
Test medium: water, gas,or oil, by customer choice
Why do the PSV Testing?
As the last link in the safety chain, safety valves require frequent testing to ensure they are in good working order and functioning properly. Mechanical parts can stick shut, wear over time and exposure to contaminants and corrosion can affect the resealing or closing of the valve seat after release, resulting in leaks. Depending on the industry in which they are used, it is recommended that they be tested at least every 1-3 years, or more frequently depending on previous inspection history.
All water-wetted parts are corrosion-proof.
Clamping pressure valve type is hold, hold press claws clamping flange, no external influence on the test valve.
The automatic pressure acquisition system is used to detect the cracking pressure with overpressure, timeout and leakage monitoring functions, which can automatically alarm and terminate the test.
