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 maintaince.
It can be mounted whereever 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, applicable to different medium.
6)Strong wash and brush 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
