    Adoptive Standards:
    Valve Design: API 609, MSS SP-67
    Face To Face: API 609, MSS SP-67, DIN3202, BS EN558-1
    Pressure Test: API 598
    Flange Drilling: ANSI B16.1 class125, BS4504 PN10/PN16, DIN2501 PN10/PN16
    Top Flange: ISO5211
    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.
