Safety Relief Valve Tester


The SAFETY RELIEF VALVE TESTER performs SRV set pressure and seat leakage tests. Our unique ‘J’ tube design allows for a free flow of gas or water from the source to the SRV being tested providing a cushion of air under the SRV seat to prevent seat damage. The control panel is ergonomically designed 90° from the clamp fixture to provide a splash shield barrier between the operator and the clamp table.


Type of Valve:
Relief valves

Valve Clamping:
Flange clamping

Types of Tests:
Set/cracking point (water) & seat leakage (water, air, & nitrogen)
