Types of Through Conduit Valves

The through conduit gate valve is a typical parallel gate valve. Red Point® manufactures through conduit gate valves in two series: slab gate with self relieving seats, and expanding wedge construction. To reduce the operating force during opening and closing, a pressure balanced stem is part of our capabilities.

Hard Facing Disc

  • Wedge and seats are ground and lapped to a mirror finish and tightly guided to prevent dragging and seat damage
  • Body and bonnet joint accurately machined with high surface finish stem and packing chamber
  • Low emission valve technology optimized for extended service life
  • Low compression packing reduces friction and allows more room to re-torque in the field
  • Packing ring construction for excellent sealing and is also a corrosion inhibitor
  • Due to the full bore configuration the valve is piggable
  • Option: live loaded gland bolting
  • Lantern ring with double packing (upper & lower) for critical services

Red Point’s through conduit gate valves can be deployed for a wide variety of applications in the oil & gas and petrochemical industries when high quality, reliable valves are required. A few example applications include:

  • High-temperature services
  • High-cycle and switching services
  • Emergency shutdown valves
  • High-integrity pressure protection system
  • High-pressure oxygen, nitrogen, or hydrogen
  • Solids handling (powders, fines, dust, and catalysts)
  • Polyethylene or polypropylene
  • Coal conversion & gasification
  • Thermal fluids
  • Separator, filter, and drying systems
  • Compressor stations
  • On/off isolation service
  • Oil & gas manifolds
