Api 6d and api 600 special-made motorised gate valves are high-performance valves designed to handle the flow of fluids in pipelines automatically.
Automated solutions for precise, reliable, and safe flow control in demanding industrial environments.
Equipped with motorized actuators, these valves offer the advantage of remote control, enabling precise and efficient regulation of flow without manual intervention. They are widely used in industries where automation, reliability, and durability are essential, such as oil & gas, petrochemical, power generation, and water treatment.
API 6D specifies requirements for pipeline valves, including gate, ball, check, and plug valves used in pipeline transportation systems, ensuring safety and integrity under high pressure.
API 600 defines design and performance standards for steel gate valves in industrial applications, ensuring reliability in high-temperature and high-pressure environments.
API 6D & API 600 Special-Made Motorised Gate Valves provide an efficient solution for automated fluid control in industrial pipelines. Their motorised operation ensures precise flow regulation, enhances system safety, and reduces the need for manual intervention. With high resistance to pressure, temperature, and corrosion, these valves are ideal for industries such as oil & gas, petrochemical, power generation, and water treatment.
The API 6D API 600 Special Made Motorised Gate Valve is a bespoke, high-performance isolation valve tailored for demanding pipeline applications, delivering automated on-off flow control with precision engineering for oil, gas, and petrochemical systems. Conforming to API 6D for pipeline valves and API 600 for bolted bonnet steel gate valves, this Special Made Gate Valve features a custom wedge gate and motorised actuation for remote operation, ensuring tight sealing under pressures up to PN420 (Class 2500) and temperatures to 425°C. Ideal for custom transmission lines, refineries, and power plants, it provides superior corrosion resistance through forged ASTM A216 WCB carbon steel or A182 F316 stainless steel with specialized coatings.
Precision-manufactured via forging and advanced heat treatment, the API 6D Gate Valve includes an OS&Y rising stem for position indication and bolted bonnet for containment, with custom dimensions per ASME B16.34. 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 (multi-turn) compatible with 4-20mA or HART protocols for SCADA integration. The motorised design enables automated monitoring, reducing manual risks, while the full-bore wedge minimizes pressure drop (Cv up to 20,000). Testing per API 598, including 100% RT/UT and hydrostatic shell tests at 1.5x rated pressure, confirms tensile strengths above 485 MPa for cyclic loading integrity.
Tailored with Stellite hard-facing on the wedge for abrasion resistance in slurries, the API 600 Gate Valve offers NACE MR0175 for sour service and through-conduit for pigging. Custom coatings like epoxy or 3LPE enhance Corrosion Resistant Gate Valve properties against chlorides or H2S in offshore or buried lines. The electric actuator, with ATEX/Exd certification, delivers torque up to 10,000 Nm and fail-safe spring-return for emergencies. Face-to-face aligns with API 6D, ASME B16.10, and BS EN 558 for seamless retrofitting.
Compared to standard gate valves, the Motorised Gate Valve cuts operation time by 80% via automation, perfect for large, infrequent-use scenarios, outperforming ball valves in high-pressure isolation with lower leakage. Slab gate variants handle dirty services, and custom pressure-seal bonnets suit steam. Integration with DCS supports predictive maintenance, extending life by 3-5 times in Pipeline Isolation Valve duties.
Tackling custom needs like high-differential leakage, erosion, and pipeline compliance, this Special Made Gate Valve includes double-block-and-bleed and secondary seals for safety. Its bespoke design optimizes performance and cost for projects. Whether isolating gas lines or refinery units, it delivers reliable, low-maintenance Pipeline Isolation Valve solutions globally.
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.
