Butterfly Connection with flanged, wafer, welded connections and lug wafer connection. Drive the form of a manual, worm gear, electric, pneumatic, hydraulic, electro-hydraulic actuator linkage, enabling remote control and automation. Valve Co., Ltd. Shandong Everbright wide production of this type of valve application, reliable quality, no leakage, leakage phenomenon, valves, frequent switching is not stuck, rusted, the majority of chemical plants, thermal power plants, steel mills, printing and dyeing plants, food plants the best choice. BD343H flange butterfly hard seal insulation Features: 1, using three-dimensional eccentric structure, seat and disc almost no friction, with more closed more tight sealing function and wear compensating seals deputy. 2, the seal is soft and hard stacked metal sheets, with the dual advantages of metal seals and elastomeric seals. 3, sealing surface heap Stellite alloy, seal wear resistance and long service life. 4, the use of different materials, both at low and high temperature, high pressure situation, both with excellent sealing performance, valve type, and can be made into two-way sealed type. 5, can provide a variety of transmission according to user requirements. 6, the electric valve can be manual or remote centralized control of the scene, and can meet the needs arts program-controlled computer. Butterfly installation techniques and how to use equipped with flange and bolts needed to regulate the flow, there are worm gear box control. Open and close the valve more frequently, in about two months time, open the worm wheel cover, valve type, check the butter is normal, should maintain the right amount of butter. Check the connection site requires compression, which is to ensure filling of bees, but also to ensure a flexible stem rotation.
