AT type pneumatic actuator

Design Features
1. Complies with the latest international standards ISO 5211, DIN 3337, VDI/DE3, and 3845 NAMUR.
2. The extruded high-wall aluminum cylinder body, with a finely ground and hard-anodized interior, offers long service life, low mold resistance, and fast actuation.
3. The compact, modern design and a wide range of product sizes make selection more economical.
4. The actuators, with the same external structure, are available in double-acting and single-acting (spring return) styles. The single-acting version is available in both closed and open configurations.
5. A NAMUR-compliant multifunctional position indicator provides visual indication and supports installation and output of all accessories.
6. Pre-loaded springs ensure safe and easy installation and removal.
7. Piston seal materials are suitable for use in high and low temperature environments.
8. A variety of angular travel options (e.g., 120°, 135°, 180°, etc.) are available upon request. Three-position pneumatic actuators can be directly mounted on solenoid valves without the need for a connecting plate.

Operating Media
Clean, dry, or lubricated air or inert gas, compatible with the actuator's internal components and lubricant, with a non-corrosive medium and a dew point stability of -20°C. Particle size of contaminants in the medium should not exceed 30µ. When selecting a positioner, the contaminants in the medium should not exceed 5µ.
