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 rotary actuator is designed for precision control in various industrial applications. Featuring a compact design, it operates with a single-acting mechanism and a 90° swivel angle. The actuator boasts a bore size of 20mm and is suitable for high-pressure environments.

• Delivers reliable performance at operating pressures of up to 8 bar
• Supports versatile mounting positions for flexible installation
• Offers a significant torque of 14.7 Nm at nominal operating pressure
• Constructed from robust materials for enhanced durability

• Utilised for valve automation in industrial processes
• Ideal for requiring precision in actuation
• Suitable for integration within safety-related control systems
• Used in pneumatic setups for reliable motion control
• Effective in environments subject to explosive risks under ATEX regulations

It features a safety function that automatically moves to a predefined position when compressed air is cut off and the spring chamber is depleted. This guarantees safety in scenarios where immediate actuation is vital.

The actuator operates effectively within a temperature range of -20°C to +80°C, allowing it to be deployed in diverse environmental conditions without compromising performance.

Yes, the design accommodates any mounting position, providing flexibility in installation tailored to specific operational needs.
