The API 6D API 600 Manual Solid Wedge Gate Valve is a high-performance isolation valve engineered for critical pipeline applications, providing robust on-off flow control with a solid wedge design that ensures tight, bidirectional sealing under extreme pressures and temperatures. Conforming to API 6D for pipeline valves and API 600 for bolted bonnet steel gate valves, this Manual Solid Wedge Valve is ideal for transporting natural gas, petroleum, and refined products in refineries, transmission lines, and petrochemical facilities. Constructed from forged ASTM A105 carbon steel or A182 F316 stainless steel, it offers superior corrosion resistance through epoxy or 3LPE coatings, making it suitable for harsh environments like offshore platforms or sour gas service.
Manufactured via precision forging and heat treatment, the API 6D Gate Valve features an outside screw and yoke (OS&Y) rising stem for clear position indication and easy maintenance, with a bolted bonnet (BB) for pressure containment up to Class 2500 (PN420). Available in sizes from 2" to 48" (DN50 to DN1200) with flanged or butt-weld ends per ASME B16.5/B16.25, it supports temperatures from -29°C to 425°C per ASME B16.34. The solid wedge, often hard-faced with Stellite #6, provides rigidity and wear resistance against abrasive media like slurries, ensuring Class VI shutoff per API 598. Rigorous testing, including 100% RT/UT and hydrostatic shell tests at 1.5x rated pressure, confirms tensile strengths above 485 MPa, guaranteeing integrity under cyclic loading and thermal cycling.
The API 600 Gate Valve excels in full-bore flow with minimal pressure drop (Cv up to 20,000), optimizing throughput in long-distance pipelines while the manual handwheel or gear operator enables precise control with low torque. Its Corrosion Resistant Gate Valve properties resist pitting from chlorides or H2S, with optional NACE MR0175 compliance for sour service. The through-conduit design facilitates pigging for pipeline cleaning, reducing maintenance needs in Pipeline Isolation Valve applications. Face-to-face dimensions align with API 6D, ASME B16.10, and BS EN 558, ensuring seamless integration into existing systems.
In comparison to slab or expanding gate valves, the Manual Solid Wedge Valve offers simpler construction and lower cost for clean service, with 3-5 times longer life due to its rigid wedge that minimizes distortion under high loads. It outperforms knife gates in high-pressure scenarios by providing better sealing integrity, while flexible wedge variants handle thermal expansion effectively. Custom options like pressure-seal bonnets for steam service or electric actuators for automation enhance versatility across oil & gas transmission, power generation, and water management.
Addressing challenges like leakage in high-differential pressures, erosion in abrasive flows, and compliance in pipeline transport, this API 6D API 600 Manual Solid Wedge Gate Valve incorporates double-block-and-bleed functionality and secondary seals for ultimate safety. Its value-engineered design balances performance and affordability, reducing lifecycle costs in long-term projects. Whether isolating flow in gas gathering lines or shutting off in refinery units, it delivers reliable, low-maintenance Pipeline Isolation Valve solutions for global industrial demands.
Below are typical specifications for key materials in the API 6D API 600 Manual Solid Wedge Gate Valve, focusing on ASTM A216 WCB Carbon Steel for the body, ASTM A351 CF8M Stainless Steel for trim, and Stellite #6 for hard-facing overlays. Data aligns with ASTM A216, A351, and API standards.

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.
