Bevel gear gate valve
The Bevel Gear Gate Valve is a manually operated gate valve equipped with a bevel gear gearbox, specifically designed for large-diameter pipelines and high-pressure applications where direct handwheel operation becomes difficult. The bevel gear mechanism significantly reduces operating torque, enabling smooth and efficient opening and closing of the valve.
