The API 6D API 600 Manual Gate Valve is a high-performance isolation valve engineered for demanding pipeline applications, providing reliable on-off flow control with minimal pressure drop in oil, gas, and petrochemical systems. Conforming to API 6D for pipeline valves and API 600 for steel gate valves, this Manual Gate Valve features a flexible wedge gate and bolted bonnet construction for tight sealing and durability under high-pressure conditions up to PN420 (Class 2500) and temperatures to 425°C. Ideal for transmission lines, refineries, and power plants, it ensures safe shutoff while offering superior corrosion resistance through premium materials like ASTM A216 WCB carbon steel or CF8M stainless steel.
Manufactured with precision forging or casting, the API 6D Gate Valve undergoes rigorous heat treatment and 100% non-destructive testing (RT, UT, MT, PT) to meet ASME B16.34 pressure-temperature ratings. Available in sizes from 2" to 48" (DN50 to DN1200) with flanged or butt-weld ends per ASME B16.5/B16.25, it supports OS&Y (outside screw and yoke) rising stem for clear position indication and easy maintenance. The flexible wedge design compensates for thermal expansion, preventing jamming in high-temperature services, while metal-to-metal or resilient seats ensure Class VI shutoff per API 598. Its full-bore configuration minimizes turbulence, optimizing flow efficiency in Pipeline Gate Valve applications.
The API 600 Gate Valve excels in bidirectional sealing against high differential pressures, with optional Stellite hard-facing for abrasion resistance in slurries or corrosive media. Coatings such as epoxy or 3LPE enhance external corrosion resistance, protecting against soil or atmospheric exposure in buried or offshore pipelines. Manual operation via handwheel or gear operator provides precise control, with low torque requirements supporting automation upgrades. Tensile strengths above 485 MPa and yield strengths of 250 MPa guarantee structural integrity under cyclic loading, making it suitable for API 6D-compliant pipeline transportation of natural gas, petroleum, and refined products.
Compared to ball valves, the Manual Gate Valve offers superior longevity for infrequent cycling, with 3-5 times the service life in isolation duties due to its robust wedge mechanism. It outperforms knife gates in clean fluids by reducing erosion, while slab gate variants handle dirty services effectively. Custom features like pressure-seal bonnets for high-temp steam or through-conduit designs for pigging ensure versatility. The valve's adherence to EN 1982 or MSS SP-81 standards broadens global applicability, from upstream drilling to downstream refining.
Addressing challenges like leakage in high-pressure lines, thermal distortion, and media erosion, this Corrosion Resistant Gate Valve incorporates double-block-and-bleed capabilities and secondary seals for ultimate safety. Its value-engineered design balances performance and cost, reducing operational expenses in long-term pipeline projects. Whether isolating flow in gas transmission or shutting off in petrochemical processes, the API 6D API 600 Manual Gate Valve delivers unmatched reliability, efficiency, and compliance for critical industrial operations.
Engineered for high-pressure pipeline isolation with API-compliant design and corrosion resistance.
Gate valves have a simple design, widely used in low pressure-drop services. Their full-port design ensures unobstructed flow and no pressure drop, while also allowing pipeline cleaning with a pigging system.
A resilient seated gate valve with a non-rising spindle consists of the following parts. The body is the largest element of the valve, with the bonnet bolted for cleaning and maintenance. The wedge slides down to press the valve seat for complete shutoff and moves upward to allow flow. Over the last century, the construction has remained consistent, with improvements in service life, sealing performance, and corrosion resistance.
Modern gate valve bodies are more compact and sleek, enabling installation in limited space conditions while maintaining durability and efficiency.
Moves vertically to open or close, sealing against the seat for shutoff.
Made of ductile iron, it is the main housing that contains the fluid flow.
Ensures tight sealing when the wedge presses against it.
Transfers rotational motion to vertical movement of the wedge.
Supports the stem to reduce wear during operation.
Bolted to the body for easy cleaning and maintenance access.
Provides sealing around the stem to prevent leakage.
