D342X-16D341X-16D343X-16 butterfly valve butterfly valve double eccentric butterfly

Soft sealing butterfly valve plate is mounted on the pipe diameter direction. Cylindrical channel in the valve body, disc-shaped disc around the axis of rotation, rotation angle between 0 ° ~ 90 °, the rotation to 90 °, the valve is open all license conditions. The new high-life stainless steel butterfly valve characteristics and problems in the course of this general type valve should be installed horizontally in the pipeline. Soft sealing butterfly valve can be divided according to the connection flange type soft sealing butterfly valve, wafer type soft sealing butterfly valve, soft seal welded soft sealing butterfly valve is used to achieve piping system as a cut-and-flow control components, has been in the oil Many chemical industry, metallurgy, water and electricity to be very widely applied. It has been known butterfly valve technology, the seal forms enclosed structure, sealing material for rubber, PTFE and so on. Since the structure of the restrictions, suitable for high temperature, high pressure and corrosion resistance, abrasion resistance and other industries. Present a more sophisticated three eccentric butterfly valve is metal seal butterfly valve, valve and seat components for the piece, the valve seat sealing surface layer welding temperature, corrosion resistant alloy material. Multilayer soft stacked ring fixed in the valve plate, this butterfly valve in comparison with conventional high temperature, easy operation, open and close without friction, closed with the transmission of the torque increases to compensate for seal, to improve a butterfly Advantages of sealing performance and extend the life of
