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 precise control in automation systems. With a compact form factor, it features a 300mm bore and offers a 90-degree swivel angle, making it ideal for various industrial applications. It operates within a maximum input pressure of 8 bar and is constructed to withstand harsh environments while delivering efficient performance.

• Single-acting mechanism ensures reliability in operation
• Maximum torque of 221 Nm at nominal operating pressure
• Versatile mounting position suits diverse installation scenarios
• Compatible with ISO 5211 for standard valve connections
• Lightweight design at 12880g facilitates easier handling

• Ideal for valve automation in chemical processing
• Utilised in packaging machines for precise lid placement
• Used in assembly lines requiring accurate movements
• Suitable for in explosive environments

The actuator operates effectively within a pressure range of 2 bar to 8 bar with a nominal pressure of 6 bar. This ensures a consistent torque output and optimal function across various applications.

When compressed air is turned off, the actuator automatically transitions to its safety switching position due to the spring mechanism, ensuring that critical processes remain secure even during emergencies.

This actuator is rated for use in environments with temperatures ranging from -20°C to +80°C and is certified for both gas and dust explosion protection under ATEX and UKEX standards, making it suitable for hazardous locations.
