Stainless steel gate valves are one of the most common types of gate valves because of their goodcorrosion resistance. Get a wide range of applications. The gate valve is a valve that moves in the verticaldirection of the passage shaft along the closing member (baffle). It is mainly used as a cutting medium onthe pipeline. The gate valve can only be used as full-open and full-closed, and is not suitable for theadjustment of pipeline flow.
Solid wedge or flexible wedge design for excellent sealing performance.
OS&Y (Outside Screw and Yoke) design for easy identification of valve position and maintenance.
Rising stem design provides visual indication of valve position.
Bolted bonnet or pressure seal bonnet design for high-pressure applications.
Locking devices for safety and security.
Optional handwheel, gearbox, or electric actuator for manual or automated operation.
Optional extended bonnet for cryogenic applications.
Optional bellows seal for fugitive emissions control.
One of the primary advantages of stainless steel gate valves lies in their corrosion resistance properties. Stainless steel, renowned for its resistance to rust and corrosion, ensures longevity and durability even in harsh operating conditions, making these valves suitable for a diverse range of industries and applications.
Moreover, stainless steel gate valves are available in various sizes, pressure ratings, and configurations, allowing for seamless integration into different piping systems. Whether in petrochemical plants, water treatment facilities, or industrial processes, these valves provide versatile and dependable fluid control solutions.
Body: The body of the gate valve is typically made of stainless steel, which provides corrosion resistance and durability. It houses the other components of the valve and provides the main structure.
Gate/Wedge: The gate or wedge is the movable component of the valve that controls the flow of fluid. It is usually made of stainless steel as well and is designed to fit snugly into the valve body to create a tight seal when closed. The gate moves up and down within the valve to open or close the flow passage.
Stem: The stem is a threaded rod that connects the gate to the actuator (handle, wheel, or motor) located on the exterior of the valve. When the actuator is turned or operated, it moves the stem, which in turn moves the gate to control the flow of fluid.
Bonnet: The bonnet is the top portion of the valve body that encloses the stem and protects it from external elements. It is usually bolted or screwed onto the valve body and may contain packing material to provide a seal around the stem.
Packing/Gland: The packing or gland is a sealing mechanism located around the stem where it exits the bonnet. It prevents leakage of fluid from the valve body along the stem. Packing material, often made of PTFE or graphite, is compressed around the stem by a gland nut to create a tight seal.
Seats: The seats are sealing surfaces located on either side of the gate that come into contact with the gate to form a tight seal when the valve is closed. They are typically made of stainless steel or a resilient material such as EPDM or PTFE to provide a secure seal and prevent leakage.
