Description Material Performance Product Size Specifications

The structure characteristics of the plunger valve is composed of a stainless steel plunger and two sealing rings are flexible, and can maintain the sealing ring on the metal frame fixed distance, like a cork generally inserted into the sealing piston to form a cylindrical contact two sealing ring, the sealing area is not comparable to the traditional cut-off valve sealing, good special effects, on the sealing ring to prevent leakage, sealing ring in the sealing effect, if used for a long time after the leak, by adjusting the fixing bolt on the valve cover pressure (the first valve port is closed so that the sealing ring on the end) than the pressure increase, caused by the force to increase the sealing ring, restore the organ to leak, I plant after several interference with dense group of sealing test, determine the interference seal value is reasonable, the reciprocating motion of millions of times, still can be completely reliable Provide good sealing effect.
Note: parameters are for reference only, or are not full. Valve can be used in accordance with the requirements of different pressure, material, diameter, drive, etc.. Specific please contact or online advisory contact.
