ATEX double action or single action rack and pinion pneumatic rotary actuator for butterfly and ball valves
Our advantage:
Controlling The Speed Of Pneumatic Actuators And Keeping Actuator
Speed Constant
It is frequently helpful to know the basic practices for
controlling pneumatic actuator speed, as well as a few guidelines
for gathering the information to properly select the components.
If you are looking to control the speed of the pneumatic actuator in your application, the most effective way is to use a speed control valve or flow control valve to vary the amount of flow out of the exhaust port of the actuator.
In order to adjust the speed, the flow must be controlled, where as adjusting the force of the actuator should be handled by controlling the pressure. Adjusting the pressure may have an effect on the speed, but is not a recommended method to control the speed.
To maintain a constant speed for your pneumatic actuator, size a fixed orifice for a constant flow on the exhaust port of the pneumatic actuator in conjunction with a pressure regulator on the input. The pressure regulator will ensure that the output pressure will remain constant (relatively) given a varying input pressure. The fixed orifice will maintain the desired flow to maintain the proper speed for your pneumatic actuator.

AT series pneumatic actuators statement of usage and selection
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.
Excellent compact and modernized construction along with multi specifications makes the selection both economic and beneficial.
All acting surface adopt high quality bearing resulting in low friction, high cycle life, and no noise
The two independent external stroke adjustment bolts can easily and precisely adjust ±5°at both open and close directions.
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.
Multi function indicator with NAMUR is convenient for mounting accessories.
Pre-compressed load spring is convenient for safe mounting and tear down procedures.
Die-casting aluminum pistons and end caps have high intensity and light weight.
Different O-rings materials are available for high and low temperature.
AT series Pneumatic Actuator is made of dual pistons driven by racks and pinions. There are two models. One is Dual Acting model, and the other is Spring Return model, which can suit various flammable, corrosive, dusty, strong magnetic field, radiation, vibration corrosive environment indoor or outdoor.
