Soft-Sealed Pneumatic Butterfly Valve with Actuator​

Pneumatic actuator


Since voltage and current are easier to control than air pressure, electric actuators can accurately control their position and repeat that position with the same motion profile. Pneumatic actuators are typically chosen for simple end-to-end positioning applications since they simply cannot achieve the same accuracy and repeatability as electric actuators.

Electric actuators use either servo motors or stepper motors, which already offer high stop accuracy and torque control capability. The holding torque from the motors also prevents position drifting.

One thing I noticed is that pneumatic actuators are gradually becoming more advanced as they adopt similar controls as electric actuators, but they would still require additional sensors and programming to achieve close to the "off-the-shelf" accuracy and repeatability of electric actuators while taking up I/O on a PLC.

Pneumatic actuators statement of usage and selection

  1. Through research development and design AT series pneumatic actuators incorporate the latest technology materials and innovative idea. The product proudly boasts the following features.
  2. Full conformance to the latest specifications: ISO5211,DIN3337 and VDINDE-3854,NAMUR.
  3. The extruding high intensity aluminum body possesses a honed internal surface coated with hard anode oxygenation for long life. Low coefficient of friction and swift performance.
  4. Excellent compact and modernized construction along with multi specifications makes the selection both economic and beneficial.
  5. All acting surface adopt high quality bearing resulting in low friction, high cycle life, and no noise
  6. The two independent external stroke adjustment bolts can easily and precisely adjust ±5°at both open and close directions.
  7. Same outline actuators have the functional modes of double acting and single acting (Spring -Return). The Spring-Return has the normally-open and normally-close styles.
  8. Multi function indicator with NAMUR is convenient for mounting accessories.
  9. Pre-compressed load spring is convenient for safe mounting and tear down procedures.
  10. Die-casting aluminum pistons and end caps have high intensity and light weight.
  11. Different O-rings materials are available for high and low temperature.
  12. Solenoid valves are easily mounted without any connecting plank.
