Description Material Performance Product Size Specifications

Plunger valve is composed of valve body, valve cover, valve stem, plunger, guide, seal ring, hand wheel and other parts. When the hand wheel rotation, through the stem to drive the plunger in the guide sleeve and the piston reciprocating motion, the end of the oblique cone surface and the valve seat surface to complete the valve opening and closing function.
In the valve plunger and the seal ring used between the interference fit, by adjusting the flange bolt preload, the lateral force and the body sealing ring generated by the compression of the cylindrical hole in Mianzhu sealing, to ensure the valve seal. Put an end to the internal leakage.
Because the sealing ring is made of a new type of high resilience and high wear resistance, a new type of sealing material is used, so the seal is reliable and durable, thereby increasing the service life of the valve.
The valve combined with the advantages of no leakage of the valve and the valve opening and closing fast characteristics, to become a novel structure, a wide range of new products. Its advantages far better than the ordinary cut-off valve.
