Product description
Parameters

Pneumatic multi-layer metal hard seal butterfly valve series products are long-life, energy-saving butterfly valves. Its structure is designed with three-dimensional weaving principle, and the valve seat adopts a multi-layered structure that is compatible with hard and soft seals. It has superb processing and advanced technology. This product consists of valve body, butterfly plate, multi-level valve seat, stem, transmission mechanism and other major components.

Since the butterfly valve of this product adopts a three-dimensional eccentric principle design, the space motion trajectory of the sealing surface is idealized, the sealing surfaces are free of friction, no interference, and the sealing material is properly selected, so that the sealing and corrosion resistance of the butterfly valve are achieved. , high temperature resistance and wear resistance have been a reliable guarantee. Its main features are as follows:

1, the opening torque is small, flexible and convenient, saving energy.

2, three-dimensional structure of the core, so that the more tightly closed butterfly, its reliable sealing performance, to achieve no leakage.

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

Pneumatic multi-level metal hard seal butterfly valves are therefore widely used in pipelines of corrosive media such as metallurgy, electric power, petroleum, chemical industry, air, coal gas, combustible gas, and water supply and drainage.
