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.

Design

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
