High performance butterfly valve drive foams include manual, worm gear, pneumatic, hydraulic, electric, electro-hydraulic linkage and other actuators for remote control and automatic operation. metal hard seal butterfly valve series products are long life energy-saving butterfly valve. Its structure adopts 3D core design principle, the seat adopts multi-layer structure, compatible with hard and soft seal, exquisite technology and advanced technology.

 

High performance butterfly valves are composed of key components such as body, disc, multistage seat, stem and drive mechanism. Therefore, high performance butterfly valves are widely used in metallurgy, electric power, petroleum, chemical industry, air, natural gas, combustible gas, water supply and drainage systems and other corrosive medium pipelines.

 

High performance butterfly valve features

 

 

High performance butterfly valve adopts the principle of three-dimensional eccentric design, so that the sealing surface of the space movement trajectory idealized, no friction or interference between the sealing surface and the sealing material correct selection. Ensure the sealing performance, corrosion resistance, high temperature resistance and wear resistance of butterfly valve. Its main features are:

 

1. Small opening torque, flexible and convenient, labor saving and energy saving.

 

2, the three-dimensional core structure makes the butterfly plate more tight, reliable sealing performance, and will not leak.

 

3, high pressure resistance, corrosion resistance, wear resistance, long life, etc.
