Portable In-Line Pressure Relief Valve Testing Device
Scope
The Ultrastar-LFM is a microprocessor controlled lift assist device designed to establish set pressure, in-line, on all spring loaded pressure relief valves, with an exposed threaded spindle. A fully self-contained electro-hydrolic power unit offers complete control during the test cycle.
Provided are a set of threaded spindle adapters that simply screw onto the valve spindle. A lightweight yoke assembly clamps to the valve bonnet/boss and the technician remotely closes the custom robotic gripper onto a threaded spindle adapter. From the same remote location the entire test is performed. All data parameters are acquired in "real time" and trigger in automatic or manual mode. The system is preloaded with seat areas for most valve types. (note: If a valve being tested is not in the database, a true area can be developed with the proper valve characteristics).
