D943H-16C Electric flange butterfly valve introduction
D943H-16C Electric flange butterfly valve is usually made up of angular stroke electric actuator (0-90° partial rotation) and butterfly valve through the whole mechanical connection, after installation and debugging together.And the structure is simple, small volume, light weight, only by a few parts.It only need to rotate 90° can be opened and closed quickly, easy to operate, and D943H-16C Electric flange butterfly valve has fluid control characteristics.The precise J-shaped elastic sealing ring and three-eccentric multi-layer metal hard sealing structure are widely used for regulating flow rate and broken flow body in industrial pipelines with medium temperature ≤425℃, such as gold, electric power, petrochemical industry, water supply and drainage industry and municipal construction industry.D943H-16C Electric flange butterfly valve adopts three eccentric structure, the electric butterfly valve seat and disc sealing surface are made of different hardness and stainless steel, with corrosion resistance and long service life, the valve has two-way sealing function.

D943H-16C Electric flange butterfly valve feature
1. D943H-16C Electric flange butterfly valve is simple in structure, compact, light in weight, easy to install and disassemble, and convenient in maintenance.
2. D943H-16C Electric flange butterfly valve adopts stainless steel "U" type sealing ring, which has certain elasticity. No matter in high temperature or low temperature, it and butterfly plate have excellent sealing performance.
3. Through strict calculation, the triple eccentricity of the butterfly valve shows that there is almost no friction between the "U" seal ring and the butterfly plate, which has a long service life and the function of getting tighter and tighter.
4. The sealing surface of D943H-16C Electric flange butterfly valve disc is surfacing with cobalt-based hard alloy, which is resistant to wear and has a long service life.
5. D943H-16C Electric flange butterfly valve has a unique structure. The "switch" can be completed only by turning the stem 90°.Flexible operation, convenient, labor-saving, not affected by the medium pressure, reliable sealing performance.
6. High temperature, low temperature and corrosion resistance.
