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 engineered for precision control in automation applications. Designed with a compact form factor, it features a 20mm bore and a 90° swivel angle, allowing for efficient operation in limited spaces. The unit operates under a maximum input pressure of 8 bar, ensuring reliable performance in various environments.

• Single-acting operation supports practical integration into systems
• Compact design enhances space efficiency in installations
• High-pressure capability accommodates demanding applications
• End-position adjustment range allows for precise alignment

• Utilised in valve control for pneumatic systems
• Effective in assembly automation processes
• Suitable for controlling equipment in packaging machines
• Integrated into rotary motion systems for process control
• Operates effectively in industrial equipment requiring precise actuation

The 90° swivel angle allows for efficient control over devices within a compact range, making it ideal for applications requiring limited motion. This precision aids in seamless integration within various automation systems.

The design incorporates a safety function that switches to a defined position when compressed air is turned off, using spring force to activate. This feature prevents unintentional movement and enhances overall operational safety.

Yes, it operates effectively between -20 °C and +80 °C, ensuring reliability in harsh environments. This temperature range makes it suitable for various industrial applications, regardless of external conditions.

Regular inspection of seals and lubrication of moving parts is recommended to maintain performance. Ensuring the actuator is kept free from contaminants will also help prolong its lifespan and reliability.
