Api 6d and api 600 manual solid wedge gate valves are essential components in controlling the flow of fluids in pipelines, particularly in high-pressure environments.
Api 6d and api 600 manual solid wedge gate valves are essential components in controlling the flow of fluids in pipelines, particularly in high-pressure environments.
Reliable solutions for industrial fluid flow control, designed to withstand high-pressure and high-temperature conditions.
API 6D & API 600 Manual Solid Wedge Gate Valves offer a reliable solution for controlling fluid flow in industrial pipelines. Their solid wedge design, manual operation, and ability to withstand demanding conditions make them ideal for applications in oil & gas, petrochemical, and power generation. With features such as corrosion resistance and low maintenance requirements, these valves are a cost-effective choice for long-term service.
API 6D covers pipeline valves including gate, ball, check, and plug valves used in pipeline transportation systems, ensuring performance under high-pressure and harsh conditions.
API 600 specifies the requirements for steel gate valves with flanged or butt-welding ends, designed for high-temperature and high-pressure services.
The API 6D API 600 Motorised Gate Valve is an advanced isolation valve designed for automated on-off flow control in demanding pipeline applications, integrating electric actuation for remote operation and precise shutoff in oil, gas, and petrochemical systems. Conforming to API 6D for pipeline valves and API 600 for bolted bonnet steel gate valves, this Motorised Gate Valve features a flexible or solid wedge gate and rising stem (OS&Y) for reliable sealing under high pressures up to PN420 (Class 2500) and temperatures to 425°C. Ideal for transmission lines, refineries, and power plants, it ensures enhanced safety and efficiency through automation, with superior corrosion resistance via materials like ASTM A216 WCB carbon steel or CF8M stainless steel and protective coatings.
The API 6D Gate Valve is precision-forged or cast with heat treatment for optimal strength, undergoing 100% non-destructive testing (RT, UT, MT, PT) to meet ASME B16.34 ratings. Available in sizes 2" to 48" (DN50 to DN1200) with flanged or butt-weld ends per ASME B16.5/B16.25, it supports electric actuators (quarter-turn or multi-turn) compatible with 4-20mA, HART, or Modbus protocols for SCADA integration. The motorised design enables remote monitoring and operation, reducing manual intervention risks, while the full-bore wedge gate minimizes pressure drop (Cv up to 20,000) for efficient flow. Testing per API 598, including hydrostatic shell tests at 1.5x rated pressure, confirms Class VI shutoff and tensile strengths above 485 MPa.
Enhanced with Stellite hard-facing on the wedge for abrasion resistance against slurries or corrosive media, the API 600 Gate Valve offers NACE MR0175 compliance for sour service and through-conduit options for pigging. Coatings like epoxy or 3LPE bolster Corrosion Resistant Gate Valve properties, protecting against chlorides or H2S in offshore or buried pipelines. The electric actuator, with explosion-proof enclosures (ATEX/Exd), provides torque up to 10,000 Nm and fail-safe features like spring-return for emergency closure. Face-to-face dimensions align with API 6D, ASME B16.10, and BS EN 558, ensuring easy retrofitting.
Compared to manual gate valves, the Motorised Gate Valve reduces operational time by 80% through automation, ideal for large-diameter, infrequent-use scenarios, while outperforming ball valves in high-pressure isolation with lower leakage rates. Slab gate variants handle dirty services effectively, and custom pressure-seal bonnets suit steam applications. The valve's integration with DCS systems supports predictive maintenance, extending service life by 3-5 times in Pipeline Isolation Valve duties.
Tackling issues like manual operation hazards, erosion in abrasive flows, and compliance in pipeline transport, this API 6D API 600 Motorised Gate Valve incorporates double-block-and-bleed and secondary seals for safety. Its automated design enhances efficiency in remote locations, balancing performance and cost for long-term projects. Whether isolating gas transmission or shutting off refinery units, it delivers reliable, low-maintenance Pipeline Isolation Valve solutions for global demands.
Engineered for automated high-pressure 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.
