A flange plunger valve is composed of valve body, valve cover, valve stem, plunger, hole holder, sealing ring, handwheel and other components. When the handwheel rotates, the valve stem drives the plunger to reciprocate up and down in the middle of the hole frame to complete the opening and closing function of the valve. Currently, flange plug valves are widely used in the petrochemical, chemical, coal gas, natural gas, liquefied petroleum gas, HVAC industries, and general industries.

Advantages of flange plunger valve:

1. In the flange plunger valve, an interference fit is used between the plunger and the sealing ring. By adjusting the flange bolts in the cover, the lateral force generated by the compression of the sealing ring is sealed with the hole surface in the valve body and the outer circle of the plunger, thereby ensuring the sealing performance of the valve, preventing internal leakage, and achieving rapid opening and closing of the valve with a small opening torque;

2. Due to the use of non-toxic new sealing materials with strong resilience and high wear resistance in the sealing ring, it can withstand long-term high temperature and high pressure without losing elasticity, making the sealing performance reliable and durable.
