INTRODUTCTION

ADVANTAGES

  • Strong pressure bearing capacity of valve body wall

    Valve body wall thickness to meet the requirements of GB 26640, thick thickness, pressure strength is guaranteed.

  • The seat has a long service life

    Valve seat is made of imported rubber, with 50% rubber content, long service life and more than 10000 opening and closing times.

  • Wide edge seat with reliable sealing performance

    Convenient installation of valve, wide contact surface with flange boss on pipeline, reliable sealing performance.

  • Valve shaft support is strong, axial sealing is reliable

    Valve shaft and valve body with 4 oil-free bearings, 3 O sealing, valve shaft support more powerful, more reliable axial sealing.

  • Heat-shrinkable film for independent packaging

    PE thermal shrinkable film is used to package the valve independently, and built-in desiccant, to isolate air dust, avoid damp pollution valve.

  • The bolt has strong corrosion resistance

    The bolt is made of 304 material, which has stronger corrosion resistance.

FEATURES

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.
