Q946F electric four-way valve,

Shanghai crown ring Valve Manufacturing Co. production of electric four-way valve, Q946F electric four-way valve in the exploitation of oil, gas, coal and ore, refining, processing and pipeline systems; Ball in chemical products, pharmaceutical and food production species; in hydropower, thermal power and nuclear power production system; ball in cities and industrial enterprises to drainage, heating, and gas supply systems; the ball in farmland irrigation and drainage systems; and to be widely used in metallurgy production system. I. Product Overview: 4-way valve in the exploitation of oil, gas, coal and ore, refining, processing and pipeline systems; Ball in chemical products, pharmaceutical and food production species; hydropower, thermal power and nuclear power production system; Ball in cities and industrial enterprises to drainage, heating, and gas supply systems; the ball in farmland irrigation and drainage systems; and to be widely used in metallurgy production system is a production construction, national defense and people's lives closely related to important mechanical products. Valve closed piping system in various types of seed used to cut off or connected media stream, the medium in accordance with a predetermined program delivery to each designated point. Second, the performance parameters and the main dimensions: ball valve stem gasket sealing surface temperature suitable packing medium WCB 1Cr13 1Cr13 1Cr13 Stellite body material stainless steel and flexible graphite flexible graphite 08 F304 F316 soft steel braided flexible graphite graphite -29 -425 ℃ water, steam, oil WC6 15CrMo 15CrMo -29-425 ℃ WC9 25Cr2MoV 25Cr2MoV LCB 304 304 -46-354 ℃ CF8 304 304 -196-600 ℃ part of the acid, alkali CF3 304L 304L CF8M 316 316 CF3M 316L 316L three Features and advantages: 1, manually pressing the handle portion may be steel or cast stainless steel handle. The handle has a limit structure, the valve open, closed position limit is set, when the valve used on critical devices, can be locked with a lock switch on the stopper position to avoid misuse. 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 with the handle, versatile, easy disassembly. With anti blowout stem structure. 3. The selection of braided valve packing, flexible graphite seals or tetrafluoroethylene-ene ring, so that the stem reliable seal lubrication under certain circumstances. 4, if necessary, the ball valve can be designed as anti-static structure, a conductive spring between the ball and the stem, stem and the body, avoid static spark igniting flammable substances, ensure system security. 5. Sealing forms. Depending on the conditions can use soft seal and hard seal, seat dampers and other structures; DN150 following is float form, DN200 or less fixed in pellet form. 6, valve seat may be provided at the secondary seal structure, the stem portion of the valve seat and the installation of grease valves, emergency situations can be temporarily sealed, and according to the need of stem extension was a suitable place for laying underground.
