Our gear operation flat gate valves are designed for precise flow control in demanding industrial environments. These gate valves are operated manually using worm gears that provide a mechanical advantage in torque, reducing the amount of work required to cycle the valve.
Worm Gear Mechanism: Our valves utilize worm gears that create a mechanical advantage in torque, making them easier to open and close with minimal effort.
Manual Operation: Gear-operated valves are hand-operated, offering simple control over the flow of liquids or gases.
Durable Construction: Constructed with top-mounted stem nut design to ensure the valve remains operational even when the handwheel is damaged due to corrosion.
Reliable Sealing: The packing is made of flexible graphite material, ensuring reliable sealing performance even after extended use.
Automatic Gate Correction: The stem is connected to the gate by a T-groove, allowing the gate to self-align and seal correctly if offset by medium impact.
Gear operation flat gate valves are typically used in:
High-stress and large size situations where manual operation is required .
Applications involving the control of water, oil, natural gas, and other fluids.
Industrial processes where high torque is needed for valve operation.
Small Flow Resistance: The body structure is simple, and the flow resistance is minimal when fully open.
Versatile Flow Direction: Can be used in ring network pipelines where the flow direction of the medium is not limited.
Durable Sealing Surface: The sealing surface is less eroded by the working medium compared to other valves.
