Bevel gear welding gate valve
The Bevel Gear Welding Gate Valve is designed for critical industrial pipelines requiring high torque operation and minimal leakage. Equipped with a robust bevel gear mechanism and fully welded ends, it ensures safe, reliable, and long-lasting performance under high-pressure, high-temperature, and abrasive fluid conditions.
Bevel gear welding gate valve
Bevel Gear Welding Gate Valves are engineered for high-pressure, high-temperature, and heavy-duty industrial pipelines. The bevel gear operator provides mechanical advantage, enabling smooth operation for large-diameter valves and high-torque applications. Fully welded body construction eliminates flange leakage, enhancing structural integrity and safety.
Constructed from forged or cast alloy steel with hard-faced sealing surfaces, these valves withstand thermal cycling, erosion, and corrosive fluids, making them ideal for power generation, petrochemical, oil & gas, and industrial steam systems.
We offer full OEM and ODM services for Bevel Gear Welding Gate Valves, customized to project or system requirements.
Bevel Gear Welding Gate Valves are manufactured under strict quality systems and can be supplied with:
