Wafer universal butterfly valve, cast iron butterfly valve
*Brief introduction:
Butterfly valve is mainly consisted of body, stem, disc, seat and driver(lever, gearbox, pneumatic and electric actuator) and so on. On off and controlling flow of valve are made by turning stem and disc together.
*Product advantages:
1) Small in size and light in weight and maintenance, it can be mounted wherever needed.
2) Simple, compact structure, quick 90 degree on-off operation.
3) Disc has two-way bearing, perfect seal, without leakage under the pressure test
4) Flow curve tending to straight-line, excellent regulation performance.
5) Various kinds of materials, applicablbe to different medium.
6) Strong wash and brish resistance and can fit to bad working condition
7) Center plate structure, small torque of open and close.
8)Long service life, standing the test of ten thousands opening and closing operation.
9) Can be used in cutting off and regulation medium.

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.
Application:
Water Treatment Plant/ Drilling Rigs/ Paper Industry/ Gas Plant/ Sugar Industry/ Cooling Water Circulation/ Breweries/ Heating & Air Conditioning/ Chemical Industry/ Pneumatic Conveyors/ Waste Effluent Treatment Plant/ Compressed Air
