Pneumatically operated butterfly valves, CLAMP DIN 32676 (C-C)
Pneumatic single-acting actuator (air/spring) is used for opening and closing direct valves with compressed air (recommended value for safe opening of the damper is 5 - 7 bar). 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).
Technical Parameters of Pneumatic Actuator
- Control shaft diameter 17 mm
- Drive height with the carrier: 185 mm
- Drive diameter: 85.3 mm
- Torque: 20 Nm
- Control pressure: 4-8 bar (5-7 bar recommended)
- Working temperature: -10 °C to 100 °C
- Adjustment speed: 1.5 sec / 90 °
- Material AISI 304
A pneumatic single-acting actuator (air/spring) is used for opening and closing direct valves with compressed air (recommended value for safe opening of the damper is 5 - 7 bar). The pneumatic actuator's spring serves to close direct damper (without control air pressure) or indecreaseontrol 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 damper can also be equipped with inductive sensors to indicate the actual damper 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 that is mounted on the control shaft.
