Standard Test :

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.


Special Test :On request, any other test can be carried out according to special instruction by client.
