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.
