Gate Valves

Gate valves are ideally used to stop, allow, or throttle the flow of a process fluid and ideally suited for on-off, primarily liquid, service. The Red Point gate valves can be designed with a rising or nonrising stem design. Gate valves are designed with a Low emmision sealing unit to provide a tight seal around the stem.

The gate valve is an outside-screw-and-yoke, full bore with flexible wedge and rising or non-rising stem. Gate valves are used to shut off the flow of fluid by inserting a rectangular gate or wedge into the path of a flowing fluid. Gate valves require very little space along the pipe axis and hardly restrict the flow of fluid when the gate is fully opened enabling gate valves to offer straightway flow with very little pressure drop. Gate valves are bi-directional valves and can provide shut-off in either flow direction.

Hard Facing

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 with a design 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 a corrosion inhibitor.
Option: live loaded gland bolting
Lantern ring with double packing (upper & lower) for critical services

Standard gate valves from Red Point® 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
