Main Features of the Product

  • A variety of soft seal and hard seal seat materials to meet more process conditions
  • The valve meets NACE standard, fugitive emission function and fire test certification of API Spec 607
  • The seat can be designed with double or single piston and has lower operating torque
  • Locking devices standard on lever operated valves
  • All valves have self cavity pressure relief function to ensure the safety of the pressure in the middle chamber
  • API 622 certified live loading of packing makes valve stem sealing safer
  • For ball valves made of carbon steel, a layer of stainless steel is overlaid on the contact position between the seat ring and the valve body and the stuffing box, so as to prevent sticking and torque increase
  • PMSS special seat structure, two-layer seal, first soft seal and second hard seal ensure better performance of the product
