Through Conduit Gate Valves

Through conduit gate valves are used for applications like:

– Offshore platforms

– Onshore terminals

– Transmission lines

Common used types of medium are:

– Non corrosive liquids

– Gas

– Water

– Sour Service

– Hydrocarbon liquids or Types of Through Conduit Valves and Hard Facing Disc

Types of Through Conduit Valves

The through conduit gate valve is a typical parallel gate valve. Through conduit  Slab 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.


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.

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

Applications for Through Conduit -Slab Gate Valves

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

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

Frequently Asked Questions

What are the application areas of the Through Conduit / Slab Gate Valves?

Trough Conduit / Slab Gate Valves can be used for a wide variety of applications in the oil & gas and petrochemical industries when high quality and highly reliable valves are required.

What is the difference between Through Conduit / Slab Gate Valves?

The full bore duct design minimizes the turbolite of the flow, and when the valve is open, the pressure drop is equal to that produced by a pipe of the same diameter and length. What’s more, the valve is perfectly suited for pigging operations.

What are the generally used fluids in Through Conduit / Slab Gate Valves?

Commonly used types of fluids are:

-Non-corrosive liquids


– Substances that give off H2S and H2SO4


– Hydrocarbons
