Safety Relief Valve Testing

ASME Section I & VIII AIR, STEAM

ABBEY ROGERS offers a lift assist device that allows for the testing of safety relief valves while still in line, and operational. The AVK is an electro-hydraulic computerized testing unit that when connected to the valve records the pressure at which the valve lifts. The AVK connects to the stem of the safety valve and measures the vertical forces exerted by the spring and load train of the valve. These tests are preformed while your system is under pressure, therefore no loss of production due to removing safety relief valves. The documentation provided will satisfy ASME & Insurance inspectors.

Valve requirements for the AVK are the following: pressure under the valve, must be flanged, must be at least a 21" clearance above the valve, service must be non-liquid, and non-hazardous vapors. The AVK is ideal for testing valves in place which will determine which valves need to be pulled out of service for repair, and which can remain inline through another cycle. The AVK will reduce manpower and downtime expenses.
