Special Alloy Through Conduit Gate Valves
The special alloy through conduit gate valves are available in a wide range of sizes and pressure ratings. The unique fabricated body of the C-G4 through conduit gate valve offers maximum strength whilst reducing the overall size and weight. This results in a much lighter, compact designed pipeline gate valves.
Technical Specification:
Design Standard: API 6D
Size Range: 6’’-48’’ (DN15-DN1200)
Pressure Rating: ASME Class 150-1500
Body Materials: Carbon Steel, Stainless Steel, Ferralium
Applications: Flowlines, manifolds, pipeline transmission and distribution, metering runs, underground storage, hot tapping, waterflood, and general pipeline service.
Features:
-All internal components can be replaced without removing the valve from the line
-Bubble-tight sealing from zero to full rated pressure
-Stem Protector
-Life lubricated bearings – no routine maintenance
-Floating parallel-sided gate can’t stick, wedge or gall
-Floating spring-loaded seats always in contact with the gate
-Self-cleaning gate
-Piggable
-Metal-to-metal primary seal – protected ‘O’ ring secondary seal
-Upstream and downstream sealing under all operating conditions – full block and bleed capability
-Suited for services requiring block and bleed or double block and bleed
-Body cavity is isolated from the valve conduit when the valve is fully open or fully closed. This allows the body to be vented to the atmosphere or drained with the valve under pressure.
Options:
-Secondary seat seal
-Emergency sealant injection (seat and stem seals)
-Extended blowdown valves
-Stem extensions for operating underground
-Transition Pieces
