Fluorine butterfly, rubber lined butterfly valve used to achieve piping system as an on-off and flow control components, has been in the petroleum, chemical industry, metallurgy, water, electricity and many other fields has been very widely used. Already known in the butterfly valve technology, the sealing structure of the form of multi-sealed, sealing materials for the rubber, PTFE, etc. As the structural features of the restrictions, not suited to high temperature,BUTTERFLY VALVES high pressure and corrosion resistance, abrasion resistance and other industries. Now there is a more advanced triple eccentric butterfly valve is a metal seal butterfly valve, valve body and seat components for the Siamese, the valve seat sealing surface layer welding temperature, corrosion resistant alloy material. Multi-layer soft-stacked ring fixed in the valve plate, the butterfly valve compared with the conventional high temperature, easy operation, open and close without friction, closed with the transmission of torque to compensate for increased seal and improve the the butterfly valve sealing performance and durability advantages. Ventilation butterfly valve used in chemical, Reducing Valvesbuilding materials, power, glass industry, ventilation, environmental engineering cold or hot dust in the gas pipeline, as gases or cut off the pipeline flow adjustment control device. This type valve in the pipe shall generally be installed horizontally. 1, with the center line and short type disc structural steel plate welded structure design and manufacture of new, compact, light weight, easy to install, small flow resistance, a large circulation, to avoid the impact of high inflation, easy operation 2, even within the non- rods, bolts, reliable, Safety Valves long service life. You can multi-station installation, from medium flow impact. How it works: ventilation valve driven by a motor-driven actuator, the disc plate 90 ° range in order to achieve open and close freely rotate or adjust media flow purposes.
