Discharge half ball

FQ411F discharge valve in half with the introduction of Germany advanced technology, through digestion, increase high-tech replacement products, to improve the management level of China's equipment industry provides a novel superior products. This series of products using new nano-ceramic material valve sealing parts and wearing parts, valve products increased wear resistance, corrosion protection and sealing, greatly extending the life of the valve. Nano-ceramic seal valves its wear resistance, sealing, and can minimize leakage, environmental protection will play a positive role in promoting. Our products are widely used in petroleum, chemical, paper, metallurgy, sewage treatment and other industries in liquid, semi-fluid, syrupy liquid, air, gas, coal gas, flammable gas, solid matter powder, grain materials containing impurities of two phase fluid and easy precipitation, easy to scale, cut crystal and other special media regulation and distribution control. ??? Shanghai crown ring Valve Manufacturing Co. http://www.ghval.com/ valves, Shanghai valves, valve manufacturers, Shanghai valve plant, discharge valve manufacturers, valve manufacturers Shanghai, Shanghai famous brand FQ411F discharge valve half ball ? Features unique design, strong performance automatic compensation: a unique floating seat design, to always keep a close fitting seal seat and ball pressure ratio core. Seat in front of the sealing ports also have raised diversion body protection to avoid direct erosion of extreme pressure medium sealed aperture and long service life. ? Sealing surface wear resistance, erosion: the use of high-tech, high hardness new sealing material for the two-phase fluid containing impurities precipitate and easy, easy to scale transport control and other special media, with strong wear resistance, erosion performance, the world leading level. Especially high-tech nano-ceramic material of the sealing deputy, hardness HRA90 ~ 94, its hardness and wear resistance of the world, only a diamond can be compared with it. ? Cut the self-cleaning ability, excellent sealing performance: Special Sealing design, superior sealing deputy platoon during the opening and closing rotational movement of the opposite sex can be cut easily remove dust adhered to the surface of sealing precipitate , scaling, etc., no stuck phenomenon, which is half ball most significant features. ? Open and close rapidly, lightweight, small pressure loss: eccentric principle structure of spherical and rapid separation of sealing in the open, low coefficient of friction, easy installation and maintenance. Spool valve opens hidden in the side of the body cavity, a fluid pass-through, a large circulation area, representing the closing valves, butterfly valves damping is small, a small pressure loss. The body cavity without causing deposition medium caking dead, overcome the gate valve, ball valve, globe valve and so easy to scarring, easy to plug, easy to leak, short life and other defects, display its unique advantages can always keep the valve normally open closing and regulation. ?????? Special requirements: stem with anti-out structure, no oil, anti-static, fire, designated coating color. ?
