Butterfly Valve
Describe
Product Usage
 
D943H type PN10~PN40 electric hard sealing butterfly valve adopts precision J-shaped elastic sealing ring and three eccentric multi-layer metal hard sealing structure. It is widely used in metallurgy, electric power, petrochemical, and water supply and drainage and municipality with medium temperature ≤ 425 °C. On industrial pipelines such as construction, regulate flow and load fluid.
 
Features
 
1. The valve adopts a three-eccentric sealing structure, and the valve seat and the butterfly plate have almost no wear, and have a tighter and tighter sealing function.
 
2. The sealing ring is made of stainless steel. It has the double advantages of hard metal sealing and elastic sealing. It has excellent sealing performance in both low temperature and high temperature conditions, and has corrosion resistance and long service life.
 
3. The sealing surface of the disc plate is made of surfacing cobalt-based hard alloy, the sealing surface is wear-resistant and has a long service life.
 
4. The large-size butterfly plate adopts a truss structure with high strength, large flow area and small flow resistance.
 
5. The valve has a two-way sealing function. It is not restricted by the flow direction of the medium during installation, and is not affected by the position of the space. It can be installed in any direction.
 
6. The drive unit can be installed in multiple stations (rotated 90° or 180°) for user convenience.
