Gearbox For Valves
Valve gearboxes are mechanical actuators designed to reduce operating torque and enable smooth, controlled opening and closing of valves. They allow safe and efficient manual operation of large or high-torque valves in industrial piping systems.
Overview
Valve gearboxes are used where the operating torque of a valve exceeds manual limits. By reducing the required force, gearboxes enable a single operator to safely open and close valves with precision.
Design Features
- Robust cast iron gearbox body
- Stainless steel stem and sealing seat
- Electrostatic powder epoxy coating for corrosion protection
- Complies with EN ISO 5211 mounting standards
Operating Characteristics
- Reduces valve operating torque significantly
- Increases the number of turns required for smooth operation
- Allows controlled and secure valve positioning
- Suitable for manual handwheel or chainwheel operation
Selection Considerations
- Correct gearbox ratio must be selected according to valve torque
- Connection dimensions must match valve interface
- Technical support is recommended for optimal gearbox selection
