Pneumatic actuator, single acting and other mounting elements for valves DN50

PRINCIPLE OF SINGLE ACTUATOR FUNCTION:

The vertical air-spring (single-acting) pneumatic actuator is widely used in operations requiring a restart in a short period of time; its advantage is its rapid and accurate response. The valve is opened by compressed air.

Basic information

PRINCIPLE OF SINGLE ACTUATOR FUNCTION:

The vertical air-spring (single-acting) pneumatic actuator is widely used in operations requiring a restart in a short period of time; its advantage is its rapid and accurate response. The valve is opened by compressed air.

Pneumatic single-acting actuator (air/spring) is used for opening and closing of butterfly valves by compressed air (recommended value for safe valve opening is 5 – 8Bar). The spring of the pneumatic actuator serves for the closing of the direct damper (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. It is also possible to supplement the valve with inductive sensors to indicate the actual valve position (open/closed). This configuration allows you to control the valve via a feedback control system in which position the valve is located.

The damper position is also indicated (visually) by a mechanical indicator mounted on the control shaft.
