Through Conduit Gate Valves

Through conduit gate valves are used in applications like: offshore platforms, onshore terminals, transmission lines.

Commonly used types of medium in these applications are: non-corrosive liquids, gas, water, sour service, hydrocarbon liquids or gas.

Our through conduit gate valves are available as forged or cast valves featuring exotic material options with short delivery times.

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
