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.
