Flange Plunger Valves
Contact UsThe U41S flanged plunger valve is composed of components such as the valve body, valve cover, valve stem, plunger, orifice frame, sealing ring, and handwheel (as shown in the figure). When the handwheel is rotated, the valve stem drives the plunger to move up and down within the orifice frame, completing the opening and closing functions of the valve. In the valve, an interference fit is employed between the plunger and the sealing ring. By adjusting the flange bolts on the gland, the lateral force generated by the compression of the sealing ring forms a seal with the inner bore surface of the valve body and the outer circumference of the plunger, ensuring the valve’s sealing performance and eliminating internal leakage. Additionally, the valve requires low opening torque, enabling rapid opening and closing. Since the sealing ring is made of a non-toxic new sealing material with high resilience and wear resistance, it maintains elasticity even under prolonged exposure to high temperatures and pressures, ensuring reliable and durable sealing performance.
