Butterfly can carry mud, valves, fluid accumulation in the pipe mouth least. Under low pressure, a good seal can be achieved. Regulation performance. Disc streamlined design, the fluid resistance loss, can be described as a kind of energy-saving products. Valve Co., Ltd. Shandong Everbright wide production of this type of valve application, reliable quality, no leakage, leakage phenomenon, frequent switching is not stuck, rusted, Shandong cast steel valves, the majority of chemical plants, thermal power plants, steel plants, printing and dyeing, 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, 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. Features: 1, using three-dimensional eccentric structure, stainless steel valves, valve seal with elastic metal ring, so that the disc valve sealing surface with a uniform and reliable contact gas seal can be achieved without leakage; 2, the unique structure, valve type, flexible operation , saving, easy, long life; 3, high temperature resistance, corrosion resistance, wear three-dimensional eccentric. Valve Co., Ltd. Shandong Everbright production of such types of valves wide range of applications, reliable, no leakage, leakage phenomenon, frequent switching is not stuck, rusted, the majority of chemical plants, thermal power plants, steel mills, printing and dyeing, the best choice for food factory.
