Product details

Features
No any leakage at the contact surface of rubber and the body’s inner owing to the rubber is vulcanized at the in-side of body
Firm rubber liner without moving and rising can provide with high reliability in running operation of ten thousands circles
Reasonable bubble-less sealing design between rubber and disc can give a small torque needs, high sealing pressure
Adopts flange design with good centering capacity, this valve can be used at the end of piping, and pipe at upper or lower reaches can be removed in repairing

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.
