Gear-Operated Butterfly Valve
The gear-operated butterfly valve, also known as a gear-type butterfly valve, is designed for both shutting off and regulating fluid flow. This valve belongs to the polymer valve category and is particularly effective for controlling the flow of viscous liquids.
In systems where fluids are under high pressure, the gear-operated butterfly valve provides reliable performance. The integrated gearbox reduces the required torque, making the opening and closing process smoother and easier. This feature makes it highly suitable for industrial applications where precise control and durability are essential.

Product Application
Applications of Gear-Operated Butterfly Valve
The gear-operated butterfly valve is primarily used in the oil and petrochemical industries. Its main purpose is to increase torque and rotational power, making operation smoother and more efficient. Similar to other butterfly valves, the gear-operated type is employed for shutting off and regulating fluid flow.
This valve is equipped with a disc that controls the opening and closing of the fluid passage. The disc can rotate 90 degrees, and by turning the lever clockwise, the valve can be opened. This design ensures reliable performance in systems requiring precise flow control.
Operation of Gear-Operated Butterfly Valve
The gear-operated butterfly valve transitions from a closed to an open position with a 90-degree rotation. Its design allows it to be used in both low-pressure, low-temperature systems and high-pressure, high-temperature environments.
For example, when water pressure inside a pipeline is very high, the gear-operated butterfly valve can be used to regulate the flow effectively. The gearbox mechanism reduces the required torque, ensuring safe, efficient, and controlled operation even under demanding conditions.
