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
