Gear Operators and Gearboxes
Complete listing of multi-turn bevel and quarter-turn worm gear operators and declutchable manual overrides.
Gearboxes and worm gear operators play an important role in the operation and control of valves in many industries. They not only reduce the physical effort required to turn a valve handwheel in manually operated valves, they can also be integrated with pneumatic and electric actuators to automate valve operation and control. They are especially useful for the operation of large and/or heavy valves.

Frequently Asked Questions About Gearboxes & Gear Operators
Learn the answers to some of the most common questions about gears in valve actuation.
Gearboxes and gear operators can help amplify the torque delivered to open or close a valve. For manually operated valves, this reduces the physical effort required by an operator to turn the valve handwheel.
These devices are commonly found in marine, oil and gas, chemical processing, water and wastewater, HVAC, and pipeline applications
Additional benefits include:
• Precise control: Worm gear operators provide a high gear ratio, which allows for greater precision when controlling the flow of fluids through a valve. This can be essential in applications requiring highly accurate flow control.
• Self-locking mechanisms: Worm gear operators offer a self-locking feature that helps maintain the position of the valve when not in operation. This helps prevent accidental movement or backflow of fluids due to vibrations or pressure fluctuations.
• Mechanical advantage: Gearboxes and worm gear operators allow for the efficient transfer of power from the input side (the operator or actuator) to the output side (the valve stem). This enables the operation of very large and/or heavy valves.
