Our range includes Single Acting and Double Acting Scotch Yoke Actuators for Ball Valves, Butterfly Valves, Plug Valves, Dampers and other compatible quarter-turn applications.
Aira Scotch & Yoke Actuators are designed for applications requiring high torque, reliable operation and long service life. Our Scotch Yoke range is ATEX & CE approved and backed by a 4-year warranty, application-specific actuator selection support and 24/7 customer support.
Aira manufactures Scotch Yoke Pneumatic Actuators in multiple configurations for different valve torque, operating and fail-safe requirements. Our range covers both single acting and double acting options for industrial quarter-turn valve automation.
Each actuator configuration is designed for specific operating requirements. For exact torque output, dimensions, operating pressure and other model-specific technical information, refer to the respective product page.
A Scotch Yoke Actuator converts the linear movement of a pneumatic piston into rotary movement through the Scotch Yoke mechanism. This makes it particularly suitable for quarter-turn valve automation where high torque is required during valve opening and closing.
Aira’s Pneumatic Scotch Yoke Actuator range can be integrated with compatible Ball Valves, Butterfly Valves, Plug Valves, Dampers and other quarter-turn equipment.
Actuator selection should be based on the actual valve torque requirement, available air pressure, operating conditions, required safety factor and fail-safe requirement rather than valve size alone.
Aira offers both Single Acting and Double Acting Scotch Yoke Actuators. Both configurations are designed for quarter-turn valve automation, but their method of operation is different.
| Selection Factor | Single Acting Scotch Yoke | Double Acting Scotch Yoke |
|---|---|---|
| Operation | Pneumatic actuation with spring return | Pneumatic actuation in both directions |
| Return Movement | Spring return | Compressed air |
| Fail-Safe Requirement | Suitable where spring-return action is required | Suitable where air operates both directions |
| Movement | Quarter-turn | Quarter-turn |
| Selection Based On | Torque, air pressure, fail position & application | Torque, air pressure & application |
A Single Acting Scotch Yoke Actuator is generally selected when the application requires a spring-return action and a defined fail position.
A Double Acting Scotch Yoke Actuator uses compressed air for movement in both directions and can be selected where pneumatic opening and closing are required.
Aira’s technical team can assist in determining the appropriate actuator configuration according to the valve and application requirements.
Aira Scotch Yoke Valve Actuators are designed primarily for heavy-duty quarter-turn automation and can be used with compatible:
Ball Valves – for automated quarter-turn opening and closing in industrial piping and process applications.
Butterfly Valves – for reliable quarter-turn automation across compatible industrial flow-control systems.
Plug Valves – for applications where suitable torque is required to operate compatible plug valve configurations.
Dampers – for rotary movement in compatible industrial damper applications.
Other Quarter-Turn Equipment – where the actuator torque, mounting arrangement and operating requirements are compatible.
The appropriate Scotch Yoke Actuator should always be selected according to the torque and operating requirements of the equipment being automated.
High Torque Output
The Scotch Yoke mechanism is well suited to demanding quarter-turn applications requiring high torque during valve operation. Actual torque output varies according to the selected actuator model and operating conditions.
Single & Double Acting Configurations
Aira manufactures both Single Acting and Double Acting Scotch Yoke Actuators, allowing the actuator configuration to be selected according to the required method of operation and fail-safe requirement.
Heavy-Duty Industrial Design
Our Scotch Yoke range is designed for demanding industrial valve automation applications where reliable actuation and long-term performance are important.
Valve Automation Accessories
Depending on the automation requirement, Aira Scotch Yoke Actuators can be integrated with compatible Solenoid Valves, Limit Switch Boxes, Positioners and other pneumatic accessories.
ATEX & CE Approved
Aira Scotch Yoke Actuators are ATEX & CE approved, supporting their use in suitable industrial valve automation applications.
4-Year Warranty
Aira’s Scotch Yoke Pneumatic Actuator range is backed by a 4-year warranty, providing additional confidence for industrial valve automation applications.
Selecting a Scotch Yoke Actuator only according to valve size can result in an incorrectly sized actuator. The actual operating requirements of the valve should be evaluated before actuator selection.
Important selection factors include:
Two valves of a similar nominal size may not necessarily require the same actuator because torque requirements can vary according to valve design, operating pressure and service conditions.
Aira provides application-specific actuator selection support to help customers identify a suitable Scotch Yoke configuration based on actual valve and operating requirements.
A pneumatic actuator often forms part of a complete valve automation package rather than operating as an isolated component.
Depending on the application, Aira can support Scotch Yoke valve automation requirements with compatible:
The required accessories should be selected according to the control requirement, valve configuration, feedback requirements and operating conditions.
