| 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.
