The valve static pressure life test system has the advantage of strong universality as one set of system achieves a static pressure life test of various valves. Noises caused by high pressure gas evacuation are reduced effectively through a small-hole silencer. Reasonable linkage, remote control, adjustable interval time, the number of tests capable of being recorded and set of the solenoid valves are achieved through integration control of a PLC and a miniature relay as well as the PLC control panel. Meanwhile, the static pressure life test of non-general industrial valves is achieved.
