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 a 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 (visually) by a pin which is mounted on the control shaft.

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