Product overview

The plunger gate valve is designed and manufactured according to the original gate valve connection size. Due to the defects of external leakage, poor refolding of sealing ring and short service life, the plunger gate valve combines the advantages of no leakage of the plunger valve with the characteristics of fast opening and closing of the gate valve and high temperature and high pressure resistance, becoming a novel structure of no leakage plunger gate valve.



Product structure
1, the plunger gate valve is composed of valve body, valve cover, valve stem, plunger, guide sleeve, sealing ring, handwheel and other parts (as shown). When the handwheel rotates, the plunger is driven by the valve stem to move up and down in the guide sleeve, so that the inclined cone of the plunger end and the seat surface complete the valve opening and closing function.
2, in the valve plunger and sealing ring with interference fit, by adjusting the flange bolt preload, so that the side force generated by the compression of the sealing ring and the valve body hole surface and plunger cylindrical seal with high wear resistance of non-toxic new sealing material, so the seal is reliable, durable, thereby improving the service life.
