HIgh-performance Pneumatic Actuator

The most commonly applied actuator is the pneumatically driven actuator, because the power source – compressed air – is relatively cheap as compared to a human resource or electric or hydraulic power sources.

From a maintenance point of view, pneumatic actuators are more easily service and calibrated than other types of actuator.

Pneumatic actuators can generate substantial thrust to handle a majority of applications, including high-pressure and high-pressure-drop situations.

Pneumatic actuators also bleed compressed air to atmosphere, which is environmentally safe, when compared to hydraulics.

Most of the benefits of choosing pneumatic actuators over alternative actuators, such as electric ones, boil down to the reliability of the devices, as well as the safety aspects.

When it comes to functionality, the pneumatic actuator is viewed to be highly reliable. This is thanks largely to the high control that can be maintained on the conversion of gas to energy.

The fact that as mentioned already, they are also highly durable means that performance is of a high standard and these devices have a long life span.

Features & Benefits

⦿ Quick-Disconnect feature – permits removal of actuator without depressurizing the valve.

(This greatly reduces downtime and lost production)

⦿ Pneumatic actuators are available in two main forms; piston actuator and diaphragm actuator. They are available in single acting and double acting features. Smart positioner are available.

⦿ Pneumatic actuators are also extremely durable and can, therefore, reduce the costs required to maintain their performance. Less maintenance means a longer product lifecycle and therefore greater output.

⦿ Rising stem – provides visual indication of valve position.

⦿ External safety relief device – protects the actuator from over pressurization.

⦿ Compact design – permits easy maintenance in restricted areas.
