Electric explosion-proof hard seal butterfly valve, explosion-proof hard seal butterfly valve, hard seal butterfly valve, electric butterfly valve

Description of electric explosion-proof hard seal butterfly valve;

D943H electric flange hard seal butterfly valve is usually composed of the Angle stroke electric actuator (0-90° partial rotation) and the butterfly valve as a whole through the mechanical connection, after installation and debugging together. And the structure is simple, small size, light weight, only composed of a few parts. And only need to rotate 90° can quickly open and close, simple operation, and the valve has good fluid control characteristics. The precision J-shaped elastic seal ring and three eccentric multi-layer metal hard seal structure, is widely used in the medium temperature ≤425℃, metallurgy, electric power, petrochemical industry, and water supply and drainage and municipal construction and other industrial pipelines, used to adjust the flow and load the body. The valve adopts three eccentric structure, valve seat and plate sealing surface are made of different hardness and stainless steel, has good corrosion resistance, long service life, the valve has bidirectional sealing function, the product is in line with the national GB/T13927-92 valve pressure experimental standards.

 Electric explosion-proof hard seal butterfly valve Features:

1, the butterfly valve has simple structure, compact, light weight, easy installation and disassembly, convenient maintenance.

2, the butterfly valve using stainless steel "U" type sealing ring, has a certain elasticity in both high temperature and low temperature, it has excellent sealing with the butterfly plate.

3, the three-dimensional eccentricity of the butterfly valve, after strict calculation, "U" type sealing ring and butterfly plate almost no friction, long service life, and has the function of closing the tighter.

4. The sealing surface of the butterfly plate is made of surfacing cobalt-based hard alloy, the sealing surface is wear-resistant and has long service life.

5, the butterfly valve structure is unique, "switch" only need to turn the stem 90° can be completed. Flexible operation, convenient, labor-saving, not affected by medium pressure, reliable sealing performance.

6, high temperature resistance, low temperature resistance, corrosion resistance.
