Product Advantage:

Adoptive Standards:
Valve Design: ASME B16.34, GB/T12237
Pressure Test: API 598 , JB/T9092
Thread standard: NPT, BSP


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).
