Fully Welded Ball Valves Collection

Applied in extreme working conditions, such as in natural gas, urban heating, and long-distance pipelines, fully-welded ball valves are bound over the whole cross-section to overcome higher loads. As such, stress corrosion cracking and external contamination are actively averted to increase the service life of our valves.

Highlights

  • Fully Welding Body Structure
  • Blow-out Proof Stem
  • Fire Safe Tested Design
  • Anti-static Design
  • ISO5211 Mount Pad
  • Double Block and Bleed
  • Cavity Pressure Relief
  • Low Emission Certified
  • Low Torque Performance
  • Secure Line Flow Locking Device
  • Optional Double Piston Effect Seat Ring
  • Optional Buried Design, Extended Stem
  • Energency sealant injection device

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
