Technical Selection
Pneumatic Actuators parameters and operating conditions
Use the details below for RFQ shortlisting. Final specifications should be confirmed by exact model, catalog page and application.
| Model / series | AT series, double-acting, spring-return and quarter-turn actuator packages. |
|---|---|
| Media | Dry compressed air for valve automation. |
| Materials and seals | Aluminum actuator body with series-specific seals, bearings and mounting kits. |
| Voltage / electrical items | Actuator itself is pneumatic; limit switches, solenoid valves and positioners require separate voltage confirmation. |
| Pressure range | General control-air review range: 0.4 to 0.8 MPa. |
| Temperature range | General ambient review range: -20 to 80 C; special environments need accessory confirmation. |
Common selection mistakes
- Do not choose actuator size without valve torque and safety factor.
- Confirm ISO mounting pattern before matching accessories.
- Fail-open/fail-close logic must be specified before quoting spring-return units.
Downloads and documents
Use the category PDF or catalog page for shortlisting; for a formal quote, send model, quantity, medium, pressure, temperature, voltage, port, material and delivery timing.
Series selection
Compare double acting and spring return AT actuators
Select the required valve position on loss of air before choosing an actuator. AT-DA uses air in both directions; AT-SR adds a spring return. Size the actuator against the valve torque throughout the stroke at the available air pressure, then check mounting and accessories.
| Series and catalog | Selection starting point | Confirm before ordering |
|---|---|---|
| AT-DA double acting actuator | Rotary valve packages operated by air in both directions. | Confirm valve torque, sizing margin, minimum air pressure and mounting flange. Do not assume a defined return position on loss of air. |
| AT-SR spring return actuator | Valve packages requiring a specified spring-return position. | Specify fail-open or fail-closed arrangement, spring set and torque at both ends of the stroke. |
Selection basis: the linked Kailing model pages provide the catalog specifications, dimensions and available product PDFs. Check the exact model and operating conditions before ordering.
