F317L Gate Valve

For pipeline isolation in corrosive chemical and process environments, F317L Gate Valve Manufacturer in Nigeria can provide gate valve configurations using low-carbon F317L stainless steel where enhanced corrosion resistance is required.

A gate valve is primarily designed for full-open or full-closed isolation, with the gate moving out of the flow path when fully open to provide a relatively unobstructed passage.

F317L contains increased molybdenum compared with conventional 316L stainless steel, which can improve resistance to pitting and crevice corrosion in selected aggressive and chloride-bearing environments. Its low-carbon composition also helps reduce the risk of sensitization and associated intergranular corrosion following welding when appropriate fabrication procedures are used.

F317L Gate Valve Components

• Body: Contains the flow passage and pressure boundary.
• Gate: Moves vertically to isolate the pipeline.
• Stem: Transfers operating movement to the gate.
• Seat: Seals against the gate in the closed position.
• Bonnet: Houses the stem and upper valve components.
• Packing: Controls leakage around the stem.
• Gasket: Seals the body-to-bonnet connection.

African Valve supplies industrial valve solutions for Nigerian oil & gas, chemical processing, water-treatment and other process facilities, where F317L gate valve configurations can be considered for suitable corrosive fluid and chemical-handling duties.
