We are offering Pressure Seal Globe Valve. The Pressure Seal Globe Valve is made using carbon steel, stainless steel, and alloy steel that ensure excellent weatherability, resistance against corrosion and sturdiness. Pressure Seal Globe Valve lowers the flowing state for reducing the pressure loss caused due to the valve correspondingly. Pressure Seal Globe Valve uses flexible deformation generated by the extrusion to the metal seal ring at the bonnet to compensate the deviation of the sealing face angle generated during processing, thus ensuring reliable tightness
Construction :
- Lift is just 1/4 of the valve seat port, ensuring a short opening/closing time.
- only one sealing face exists on the valve body and disc
- The valve has back seal structure, which ensures no leakage in the stuffing box and reliable tightness.
- The valve stem sealing is realized by collaboration of flexible and woven graphite for great tightness.
