Welcome

Model 900 -Safety Relief Valve Testing System

The Model 900 is the premier Safety Relief Valve (SRV) test system in the world today. The unique “J” tube design allows for a free flow of air or water from the source to the SRV being tested so that back pressure or pressure drop is not noticeable during the setting of the SRV. Flow and ramp rates can be easily calculated using this design. This system was designed to comply with API-576 for flow characteristics and API-527 for seat leak detection.

Model 900-6, Safety Relief Valve Test System. This system performs Safety Relief Valve set pressure tests per API-RP-576
Paragraph 6.2. This test system allows the operator to perform air and/or water test on the same clamping system.
