DC-type plunger valve

560 DC-type piston valve Name: DC-type plunger valve, also known as: Y-type plunger valve Model: U45SM soft seal, U45H / Y Hard sealing applications - U45SM / U45H DC plunger valve stem driven by a plunger the guide sleeve in the upper and lower reciprocating motion of the plunger end portion oblique cone and seat cone complete valve opening and closing function. The products are widely used in water supply and drainage, gas, electricity, metallurgy, petroleum, chemical, textile and construction and other industries, in steam, water, oil, gas, gas, nitrogen, hydrogen, liquid, nitric acid, acetic acid Classes media pipeline used for opening and closing. Structural principle - the structural characteristics of the spool is made of a stainless steel plunger and the upper and lower resilient sealing ring and the metal frame to maintain a fixed distance from the upper and lower seal rings composed of columns as 塞尤 stopper generally two sealing insert ring to form a cylindrical contact seal, large sealing area of ??the traditional cut-off valve can not be comparable, the sealing ring against external leakage, lower sealing ring within seal, when leakage occurs long after, if available, by adjusting the valve cover pressure bolts of the first valve port is closed so that the seal ring side seal than the pressure increased, leading to increased pressure through so that leakage of the seal ring to resume seal. Design Advantages - DC plunger valve allows the valve cavity medium without balance transfer, unobstructed flow of the case bends, corners, flow capacity, small resistance, and straight-through flow line is Z-shaped, angular style stream Line 7 shape, as determined by the three plunger valves, flow resistance coefficient DN100mm, straight-through piston valve flow resistance coefficient was 4.1, DN100mm corner plunger valve flow resistance coefficient was 3.8, while DN100mm DC-type plunger valve flow resistance factor of 0.5, the resistance is greatly reduced. Parameters - Temperature: -20 ℃ ~ 250 ~ 425 ℃ Applicable Nominal: PN1.6Mpa Diameter: DN15-DN200
