My company mainly produces all kinds of material electric valve, butterfly valve, ball valve, globe valve, regulating valve, check valve and a variety of other actuators. Our products are widely used in electric power, petroleum, chemical, environmental, water, coal, metallurgy, paper making, building and other industries. Electric stainless steel ball valve electric four-way valve flange detail Stone commutation valve, a valve to achieve positive and negative supply is switched every 90, water supply switch once, before four valves needed, open the water supply valve 1,4, closed valve 2,3; 2,3 turned back the water supply valve, the valve closed 1,4, now with a four-way valve replaced. Stainless steel ball valve electric motor flange Stone characteristics and uses a four-way valve, fluid resistance: Connecting pipe cross-section of the sphere and the body equal and spheres connected with arc channel, the media through the sphere is fluid resistance. 2, good sealing performance: the use of PTFE seat material has a certain elastic deformation and high strength, to achieve a good sealing performance to ensure the stability of the valve. 3, long life: the valve spool and optical see-necked materials using austenitic stainless steel, seat material selection PTFE, can achieve good anti-corrosive effect, extending the life of the valve. Electric stainless steel ball valve electric four-way valve flange works "LL" type wrench or a four-way valve actuators only operate the sphere to rotate 90 degrees, while the two media flow switch, convenient and fast to achieve a multi-valve effect. Electric stainless steel ball valve electric four-way valve flange merit a manual part of the handle can be used to suppress or stainless steel casting handle. Handle has a limit structure, the valve is opened, closed position to set the limit, when the valve is used on critical devices with keyhole lockable switch positions to avoid misuse of the stopper. There are clearly marked on the handle to open and close. 2, the valve stem A182F (1Cr13) overall forged and modulation processing, hardness HB220 ~ 250. Stem connected by flat keys or splines or square deed handle, versatile, easy disassembly. Stem with anti-blown structure. 3, the valve filler chosen braided, flexible graphite seal or tetrafluoroethylene-ene ring, such that the valve stem to achieve a reliable seal under certain lubrication. 4, if necessary, can be designed as anti-static ball valve structure, providing a conductive spring between the ball and stem, stem and the body, to avoid static electricity ignition ignite flammable substances, ensure system security. 5. Sealing forms. Depending on the operating conditions can be used soft seal and hard seal seat dampers and other structures; DN150 following is a floating ball form, DN200 ball following a fixed form. 6, ball valve seat seal structure can be set to assist in the installation of the seat and the stem portion of the grease valves, emergency situations can be temporarily sealed, and can be extended as needed to fit the stem was laying underground spaces. The company promises: Miho four packages: quality, quantity, security and timely, repair, replacement or return, the packet loss. So you can rest assured sale.
