U41S Flange plunger valve is composed of body, bonnet, stem, plunger, hole frame, sealing ring, hand wheel and other parts (as shown). When the handwheel rotates, the valve stem drives the plunger to move up and down in the middle of the hole frame to complete the valve opening and closing function. Interference fit is used between the plunger and the sealing ring in the valve. By adjusting the flange bolt of the gland, the lateral force generated by the compression of the sealing ring is sealed with the hole surface of the valve body and the outer circle of the plunger, so as to ensure the sealing of the valve, eliminate the internal leakage, and the opening moment of the valve is small, and the valve can be opened and closed quickly. As the sealing ring is made of non-toxic new sealing materials with strong resilience and high wear resistance, it has the ability to withstand long-term high temperature and high pressure without losing elasticity, so the sealing performance is reliable and durable.
