Gate Valve


Gate Valve is only intended for complete open and close of flow path, not for flow adjustment. The gate moves perpendicular to the flow path centerline for flow open and close, allowing two-way flow.                                     


  • Full-bore, two-way symmetrical seal, pressure assisted seal

  • Sealing surface of gate and seat is painted tungsten carbide, delivering excellent resistance to erosion and corrosion.

  • Grease injection valve on one side of bonnet is easy to add grease.

  • Low open/close torque 

  • Double flange, threaded-end or special connections
