Pneumatic single-acting actuator (air / spring) is used for opening and closing butterfly valves with compressed air (recommended value for safe valve opening is 5 – 8Bar). The spring of the pneumatic actuator serves for closing the butterfly valve (without control air pressure) or in case of decreasing control air pressure for safe closing of the valve (damper).

To control the pneumatic actuator, the actuator must be supplemented with a pilot (electromagnetic) valve for controlling the compressed air supply. The valve can also be equipped with inductive sensors to indicate the actual valve position (open / closed). This configuration allows you to operate the damper via a feedback control system in which position the damper is located.

The position of the flap is also indicated by a pin mounted on the control shaft. The pin shows the position of the flap heart.

Pneumatic actuators are supplied with complete accessories for direct flap mounting or as a separate actuator for use with another type of 90 ° open / close valve.
