Introducing the AccuTEST System

Midwest Valve Services now uses the latest technology in pressure relief valve testing: AccuTEST. The fully automated valve test system utilizes a computer-controlled electric motor in conjunction with system pressure to verify set point. This test accurately determines if a valve lifts within set point tolerance. More details about AccuTEST.

Database of Valve Specifications

Database of Valve Specifications

The AccuTEST system is a fully automated test system with several features that make it easier and safer for technicians to test valves in the field. Utilizing the industry’s most advanced software, this fully automated system virtually eliminates the possibility of human error throughout every stage of operation, from automatic sensor calibration to output of final test results. In addition, an acoustic signature can be recorded to help verify set point while normalizing background noise. An integrated database of valve specifications from all major valve manufacturers also allows new valve specs to be entered as needed.
Set pressures automatically calculated by measuring lift force, line pressure, and acoustic trigger.
Universal mounting assembly enables use on all types of exposed spindle valves.
Load rig allows for lift forces up to 4,500 kg (10,000 lb).
