Flanged spool "Zhengzhou Danfoss valve" type structure size standards "

Piston valve is covered, stem, plunger hole frame, sealing rings, hand wheels and other parts from the body, valve. When the hand wheel is rotated by driving the plunger valve stem in the hole down the middle frame to complete reciprocation valve opening and closing function. Plunger Valve Co., Ltd., Zhengzhou Danfoss valve series: Import plunger valve, piston valve imported from Germany, the United Kingdom imports plunger valve, piston valve US imports.

Manufacturing standards: GB, American Standard, the German standard. In the valve between the plunger and the sealing ring with an interference fit, by adjusting the gland flange bolts, the seal ring compression lateral force generated in the valve body bore surface and cylindrical plunger seal, thus ensuring the valve sealing, 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. Since the surface of the plunger through the high-precision cylindrical grinding machine processing. Seal ring with elasticity, high wear resistance, non-toxic new sealing material, a reliable seal and durable. Thereby increasing the life of the valve plunger. Zhengzhou Danfoss valve plunger has been widely used in various boiler steam systems, gas, food, pharmaceutical, power generation, construction, municipal, and other fields.
