Quarter turn rotary actuators are components that are operated by compressed air which produces a rotary motion via a shaft to control the speed and rotation of attached equipment. In this scenario, the rotary actuator will turn a quarter when rotating.

This pneumatic rotary actuator is designed for precision control in industrial automation applications. Featuring a compact design, it operates at a maximum pressure of 8 bar and a rotary angle of 90 degrees. With a bore size of 120mm, this actuator ensures robust performance while effectively managing space.

• Single-acting design allows for efficient operation
• Conforms to ISO 5211 for easy mounting
• Engineered for high-pressure applications up to 8 bar
• Low air consumption per cycle enhances efficiency

• Used with valve automation systems in machining processes
• Utilised in material handling for accurate positioning
• Suitable for assembly lines requiring robust control
• Implemented in remotely operated equipment for enhanced reliability

The actuator provides an adjustment range of -5 degrees to 5 degrees for both the zero position and the nominal swivel angle, allowing for precise calibration.

It features a safety function that engages the actuator to a defined safe position when the compressed air supply is cut, utilising spring force to ensure secure operation.

At nominal operating pressure, it delivers 43 Nm torque at the 0° swivel angle and 22.4 Nm at the 90° swivel angle, making it suitable for various load applications.
