Engineered for high-pressure, large-flow, and severe-service applications, our Big Gate Valve (Large Diameter Gate Valve) series serves as the critical flow isolation solution for oil & gas, water supply, municipal infrastructure, and power generation systems. Featuring a full-port design, these industrial gate valves provide virtually zero flow resistance and minimal pressure drop when fully open, drastically optimizing system efficiency and reducing energy consumption.
Zero-Leakage & High-Pressure Sealing: Built with high-precision metal-to-metal or resilient seating to deliver reliable bidirectional shut-off under extreme pressure (Class 150–2500) and severe temperature fluctuations.
Heavy-Duty Construction: Available in cast carbon steel (WCB), stainless steel (CF8/CF8M), and duplex steel to resist corrosion, erosion, and mechanical wear—extending service life by up to 30%.
Versatile Actuation: Fully customizable with manual handwheels, bevel gears, electric, or pneumatic actuators for seamless remote automation and easy field operation.
As a trusted global industrial valve manufacturer, our large gate valves strictly comply with international standards including API 600, ASME B16.34, and DIN/BS, offering complete OEM/ODM customization and full material traceability.
Welcome to FTJ Valves, a premier China big gate valve manufacturer and worldwide exporter. Large-diameter gate valves are critical components in heavy industrial infrastructure, municipal water distribution, and large-scale fluid handling projects. Our engineering team specializes in producing robust, precision-engineered big gate valve units designed to withstand extreme pressures, harsh operating environments, and demanding flow requirements.
When sourcing a china big gate valve, system reliability and long-term durability are non-negotiable. At FTJ Valves, we build heavy-duty valves that comply strictly with international manufacturing benchmarks including API 600, API 6D, DIN, and BS standards.
High-Strength Construction Materials: Manufactured using high-grade materials including WCB cast steel, ductile iron, stainless steel (SS304/SS316), and alloy steels, ensuring excellent structural integrity under high-pressure pipeline conditions.
Low Torque & Smooth Operation: Equipped with advanced gearboxes, electric actuators, or pneumatic operators, our large gate valves are engineered for easy, low-torque operation despite high differential pressures.
Reliable Bi-Directional Sealing: Designed with resilient or metal-to-metal seating configurations to guarantee zero-leakage shut-off, reducing maintenance overhead and preventing fluid contamination.
Corrosion Protection: Coated with heavy-duty fusion-bonded epoxy (FBE) externally and internally to extend service life in underground, exposed, or marine environments.
