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
– 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
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.
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.
Commonly used types of fluids are:
– Substances that give off H2S and H2SO4
