AT‑Series Pneumatic Actuator

AT‑Series Pneumatic Actuator

The AT‑series pneumatic actuator adopts a new‑type rack‑and‑pinion transmission mechanism. It is innovatively designed based on extensive field installation and product application experience, integrating the latest pneumatic actuator technologies and applied materials. Fully proven by practical applications, our product features the following advantages:

  • High performance and high reliability

  • Broader applicable specifications and higher cost‑performance

  • Fully compliant with the latest international standards

  • Optimized industrial appearance, suitable for various application environments

Selection Scope:

A. Actuators of all specifications can be supplied with 304 or 316 stainless steel output shafts upon request.
B. For high‑temperature and low‑temperature applications, all actuators are available with corresponding FKM and silicone rubber O‑rings together with special lubricants.
C. Besides standard parallel square and diagonal square bottom output shafts, key‑type and flat‑end output shafts are also available, or supplied as specified by customers.

Quality Management:

The production of AT‑series pneumatic actuators is fully compliant with ISO9001 system requirements.
Each individual actuator is tested before delivery and assigned a unique serial number for identification and traceability.
Each actuator is packed in a suitable carton. Sufficient and detailed markings are printed on each carton for actuator protection and identification purposes.

Optional Accessories:

  • Bracket

  • Coupling

  • Solenoid valve

  • Limit switch box

  • Proximity sensor

  • Gear box (handwheel mechanism)

  • Positioner

  • Reduced‑size square output shaft available for all output shafts


Note: (A) The above‑mentioned actuator operating time is measured under the following test conditions


1. For actuators size 32 to 160

(1) Room temperature

(2) Actuator stroke: 90°

(3) Solenoid valve port size: 4 mm, flow capacity Qn400 L/min

(4) Air pipe inner diameter: 6 mm

(5) Neutral clean air

(6) Air supply pressure: 5.5 bar

(7) Actuator without any load

2. For actuators size 190 to 400

(1) Room temperature

(2) Actuator stroke: 90°

(3) Solenoid valve port size: 12 mm, flow capacity Qn5100 L/min

(4) Air pipe inner diameter: 8 mm

(5) Neutral clean air

(6) Air supply pressure: 5.5 bar

(7) Actuator without any load

Caution: If one or more on‑site parameters differ from the above, the operating time will vary accordingly.


Air consumption depends on air supply pressure, switching stroke, storage volume and number of operations. The calculation formula is as follows:


L/min = Cylinder volume (opening volume + closing volume) ×image.webp× Number of operations / min
