SHINEEAST

Safety Valve Test Machine, Pressure Relief Valve Test Bench is used for comprehensive performance testing of safety valves, including design performance tests of gas safety valve flow rate, cracking pressure, cracking pressure difference, and cracking height. The equipment has advanced design principles, and adopts the Simint data acquisition system, which can store and retain the safety valve measurement data for a long time, query and generate hard copies and archives, and can directly generate verification reports with computer database storage.

Shineeast safety valve test bench uses high-pressure air as the medium to do testing for the sealing performance, and uses Shineeast high pressure pump as the power source to realize activated pressure testing and reseating pressure testing of the safety valve.

Features of Safety Valve Test Machine

Spring safety valves, pressure relief valves, and spring stem exposed threads are widely used.

The instrument has a USB interface that can transmit the measurement data to the microcomputer to realize the scientific system management of data storage, query and display safety valve.

Equipped with an independent low pressure detection system, which can be adjusted steplessly according to the low pressure, it is more convenient to detect the low pressure safety valve and protect the precision pressure gauge from damage.
