China at Series Angular Stroke Output Single Acting or Double Acting Pneumatic Actuator

Main features:
•AT series pneumatic actuators are divided into double-acting type and single-acting type (spring return).
• Angular stroke output to meet the needs of various valves in common use with small torque rotating.
• The cylinder body is made of die-cast aluminum alloy (Aluminum alloy with hard anodic oxidation wear - resistant, anti - corrosion, long operating life).
• The bottom fixed hole is convenient for actuator to connect with the valve and make it aligned, in accordance with ISO5211/DIN3337 standard.
• Use clean air as medium, high safety factor.
• Basic design: pneumatic double piston rack and pinion transmission mechanism.
• Powerful accessory functions: single (double) electric solenoid valve, limit switch, electrical positioner, air treatment FRL and manual operating mechanism can be equipped, fully realizing automatic or manual control.
• External protection: corrosion resistance up to 500 hours in salt spray. Comply with ASTM B117 standard.
