Product Details import threaded inner plunger valve inlet thread spool outlined in the inlet thread spool is made up of body, bonnet, stem, plunger, guide, sealing rings, hand wheels and other parts (see figure). When the hand wheel is rotated by driving the plunger on the valve stem in the guide sleeve, the lower reciprocating motion, the plunger end of the oblique cone and seat cone complete valve opening and closing function. Shut-off valve in the piston and the seal between the piston ring with the interference fit, by adjusting the flange bolt preload, compression seal ring lateral force in the valve body bore cylindrical generated surface of the plunger seal, thus ensuring the tightness of valves, to prevent internal leakage. Since the sealing ring strong resilience, high abrasion resistance, non-toxic new sealing materials used, so seal reliable and durable. Thereby increasing the life of the plunger shut-off valve. Plunger valve plunger closing valves combine a little leak and shut-off valves open and close and fast become a new structure, extensive use of new products.
