Product details

Plunger type gate valve is composed of valve body, valve cover, valve stem, plunger, guide sleeve, seal ring, hand wheel and other parts (as shown in the figure). When the hand wheel rotates, the plunger is driven to reciprocate up and down in the guide sleeve by the valve stem, making the plunger end inclined conical face and seat face complete the valve opening and closing function.The plunger and sealing ring in the plunger type gate valve adopt interference fit, through adjusting the flange bolt pre-tightening force, so that the tendency force generated by the sealing ring compression and the valve body in the hole face and the cylindrical sealing of the plunger so as to wear a high non-toxic new sealing material, so the sealing is reliable, durable, thus improving the service life of the valve.Plunger valve is the design and manufacture of the size according to the original valve connection, due to leakage valve in use process, sealing ring with resilience is poorer, the characteristics of short service life, gate valve, valve plunger is a combination of leak-off advantages of plunger valve and gate valve opening and closing fast and the characteristics of high temperature and high pressure resistance, become a kind of new structure of plunger valve without leakage.
