The AT Pneumatic Actuator is an innovative angular stroke pneumatic actuator engineered to meet global industrial standards, delivering superior performance in automated valve control. Compliant with NAMUR standards, SO 5211, and DIN 3337, this actuator combines a compact design with high-strength construction—making it ideal for rotary valves like ball valves, butterfly valves, and plug valves. Featuring a high-strength extruded aluminum cylinder with hard anodized inner surface, it ensures low friction, quick response, and long service life. Whether for standard angular strokes (90°, 120°, 135°, 180°) or custom three-position configurations, the AT Pneumatic Actuator excels in industrial automation, process control, and critical applications requiring reliable actuation. Its multifunctional design, including loss-of-air reset spring (for single-acting models) and NAMUR-compatible accessories, simplifies installation and integration—making it a top choice for automation-focused industries.
Adhering to NAMUR standards (VDI/VDE 3845) and SO 5211/DIN 3337, the actuator ensures global compatibility with valves, solenoid valves, and positioners—simplifying cross-industry integration.
The extruded aluminum cylinder with hard anodized inner surface reduces friction, enabling quick movement and extended service life. Die-cast aluminum alloy components offer high strength, light weight, and corrosion resistance.
The unique external two-way travel adjustment bolt allows ±5° fine-tuning for full open/closed positions, ensuring precise valve alignment and optimal flow control.
Double-acting and single-acting models share the same external structure, enabling easy replacement without modifying pipeline or valve mounts—reducing maintenance costs and downtime.
The NAMUR standard position indicator provides visual status updates, simplifying installation and troubleshooting. It supports seamless integration with automation systems for real-time monitoring.
Optional high/low temperature-resistant sealing materials allow the actuator to operate in harsh environments—from freezing industrial settings to high-heat process lines.
Single-acting models feature a loss-of-air reset spring, automatically returning the valve to a pre-set safe position (normally open/closed) during air supply failure—enhancing system safety.
Industrial Automation Systems: Integrates with PLCs and control panels for automated valve control in manufacturing lines and process plants.
Chemical & Petrochemical Processing: Ideal for corrosive or high-pressure rotary valve control, compatible with chemical media and natural gas.
Power Generation & Energy: Regulates butterfly valves in steam pipelines and gas turbines, supporting efficient energy production.
Mining & Metallurgy: Handles abrasive media in mining operations and smelting plants.
Printing & Dyeing: Controls fluid flow in textile dyeing and printing processes, with corrosion resistance to dyes and chemicals.
Water Treatment & Environmental Engineering: Manages valves in wastewater treatment plants and water distribution systems.
Pharmaceutical & Daily Chemical: Complies with hygiene standards for precise fluid control in pharmaceutical and cosmetic manufacturing.
Suitable for custom angular strokes (e.g., 120°, 135°) and three-position actuators, meeting specialized needs in robotics, automated assembly lines, and precision process control.
It meets NAMUR standards (VDI/VDE 3845), SO 5211, and DIN 3337—ensuring compatibility with global valve and automation components.
Yes! It features NAMUR standard air nozzle connection holes, allowing direct solenoid valve installation without an adapter plate—saving time and reducing installation complexity.
Standard options include 90°, 120°, 135°, and 180°. Custom angular strokes and three-position configurations are available upon request.
Absolutely. Optional high/low temperature-resistant sealing materials enable operation in extreme temperature environments—ideal for cold storage or high-heat industrial processes.
Single-acting models include a loss-of-air reset spring. If air supply is interrupted, the spring automatically returns the valve to a pre-configured safe position (normally open or normally closed), preventing system damage.
