Aluminum Pneumatic Actuators

AP series aluminum rotary pneumatic actuators offer a modern solution for the reliable control of industrial valves in environments where compressed air is available. These actuators are designed for automating quarter-turn valves such as butterfly valves and ball valves (rotation 90° ±5°).

The AP series operates on the rack and pinion principle and is available in both double-acting and single-acting (spring return) versions. With a hard-anodized aluminum body and precision-engineered internal components, these actuators are lightweight, durable, and suitable even for corrosive or humid environments.

Designed with a focus on modularity and easy integration, they can be quickly equipped with limit switches, solenoid valves, and visual position indicators. The series offers an excellent balance between performance, size, and cost.

Key benefits of AP aluminum actuators

✅ Compact hard-anodized aluminum body – lightweight and corrosion-resistant
✅ Rack & pinion mechanism for smooth and even motion
✅ Suitable for a wide range of valves and torque requirements
✅ Available in both single-acting and double-acting versions
✅ Ready for accessory mounting according to VDI/VDE standards

Looking for a lightweight yet powerful actuator for valve automation? The AP series pneumatic actuators offer flexibility, reliability, and easy integration.
