Plunger valve

554 plunger valve Name: plunger type valve known as: plunger valve, soft sealing plug valve, hard seal valve plunger type: UZ41SM soft seal, UZ41H / Y Hard sealing applications - UZ41SM plunger valve when the hand wheel rotate, driving the plunger through the stem in the hole down the middle frame to complete reciprocation of the valve opening and closing function. The products are mainly in chemical, petrochemical, oil, paper, mining, electricity, gas, food, pharmaceutical, water supply and drainage, municipal, mechanical equipment, electronics industry, urban construction and other fields of switch, or turn off the line of medium. Structural principle - are covered by the piston valve body, valve stem, plunger hole frame, sealing rings, hand wheels and other parts. Between the plunger and the sealing ring with an interference fit, by adjusting the gland flange bolts, the seal ring compression generated by the lateral force in the valve body bore surface and cylindrical plunger seal, thus ensuring the tightness of valves , to eliminate the internal and external leakage while the valve opening torque is small, can achieve rapid valve opening and closing. Closed by a stainless steel plunger valve plunger down two flexible seals and a metal dam frame composition, sealing the plunger to achieve tight fit and seal, the plunger is inserted in the two seals, the seal area much larger than the ordinary cut-off valve; switch plunger valve plunger slowly moving ring, the contact surface hardly wear off, the plunger is inserted under the ring, cut off the flow path; when open, although departing from the plunger seal ring, but still hidden in the ring, keeping the outside world, it will not leak. Design advantage - the valve seal with new non-metallic materials, good mix overall performance, having to withstand long-term high temperature, high pressure without losing elasticity properties, besides the contact area between the plunger and seal large. Since the surface of the plunger through the high-precision cylindrical grinding machine processing; seal ring elasticity, high wear resistance, non-toxic new sealing materials used, so a reliable seal and durable. Thereby increasing the life of the valve plunger. Parameters - Temperature: -20 ℃ ~ 250 ℃ ~ 425 ℃ applicable nominal pressure: PN1.6 ~ 4.0Mpa Diameter: DN15-DN200
