Body Test: 1.5
times the working pressure with water. This test is performed after
valve assembly and with disc in half position open, it is called as a
body hydro test.
Seat Test: 1.1 times the working pressure with water.
Function Operation Test:
At the time of final inspection, each valve and its actuator
(Flow-Control Lever / Gear / Pneumatic Actuator), under goes a complete
operating test (Open/Close). This test carried out without pressure and
at ambient temperature. It ensures the correct operation of the valve /
actuator assembly with accessories such as solenoid valve, limit
switches, air filter regulator etc.
