Mental seat butterfly valve function characteristics

Mental seated butterfly valve as a component used to realize the pipeline system on and off and flow control, has been widely used in petroleum, chemical industry, metallurgy, hydropower and many other fields. In the well-known butterfly valve technology, the sealing form of the sealing structure, sealing material for rubber, PTFE and so on. Due to the limitation of structural characteristics, it is not suitable for high temperature, high pressure, corrosion resistance, wear resistance and other industries. The existing butterfly valve is a more advanced three eccentric mental seat butterfly valve, valve body and valve seat for connected components, valve seat sealing surface layer surfacing welding temperature resistant, corrosion resistant alloy material. The multi-layer soft laminated sealing ring is fixed on the valve plate. Compared with the traditional butterfly valve, the butterfly valve has the advantages of high temperature resistance, light operation, no friction in opening and closing, closing with the increase of the torque of the transmission mechanism to compensate for the sealing, improving the sealing performance of the butterfly valve and extending the service life.

mental seat butterfly valve features:

1. mental seat butterfly valve with three eccentric sealing structure, valve seat and butterfly plate almost no wear, with the more close the tighter sealing function;

2. the sealing ring is made of stainless steel, with the double advantages of mental seat and elastic seal, both at low and high temperature, has excellent sealing performance, corrosion resistance, long service life and so on;

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

4. the large size of the plate quilted structure, high strength, flow area is large, flow resistance is small;

5. with two-way sealing function, installation is not limited by the flow of the medium, also not affected by the spatial position, can be installed in any direction.
