Supply electric triple eccentric flange butterfly valve D943H-16C DN50 electric hard seal butterfly valve

Description :

1. Product Overview

　　D943H electric flange hard seal butterfly valve is usually composed of an angular stroke electric actuator (0-90 ° partial rotation) and the butterfly valve as a whole, which are mechanically connected and installed and debugged together. And it has a simple structure, small volume, and light weight, consisting only of a few parts. And it only needs to be rotated 90 ° to quickly open and close, with simple operation, and the valve has fluid control characteristics. Using precision J-shaped elastic sealing rings and a three eccentric multi-level metal hard sealing structure, it is widely used in industrial pipelines such as metallurgy, power, petrochemicals, water supply and drainage, and municipal construction where the medium temperature is ≤ 425 ℃, for regulating flow and carrying fluids. The valve adopts a three eccentric structure, and the valve seat and disc sealing surface are made of different hardness and stainless steel, which has corrosion resistance and long service life. This valve has bidirectional sealing function.

　　Features of electric explosion-proof hard seal butterfly valve:

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

　　2. This butterfly valve adopts a stainless steel "U" - shaped sealing ring, which has a certain degree of elasticity and excellent sealing performance with the butterfly plate under high and low temperature conditions.

　　3. The three-dimensional eccentricity of this butterfly valve has been rigorously calculated, and the "U" - shaped sealing ring has almost no friction with the butterfly plate, with a long service life and the function of tightening as it is closed.

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

　　5. This butterfly valve has a unique structure, and the "switch" can be completed by simply rotating the valve stem 90 °. Flexible, convenient, effortless operation, not affected by the high or low pressure of the medium, and reliable sealing performance.

　　6. Can withstand high temperature, low temperature, and corrosion.
