  • Application

Application

  • Limit switches for capturing the end positions (OPEN and/or CLOSED) of gas-tight shut-off dampers
  • Electric signals of limit switches are integrated with system control
  • Solenoid valve to provide the electric control input signal for double acting pneumatic actuators

Technical information

  • Function

The actuator moves the blades of a gas-tight shutoff damper into OPEN or CLOSED position. The easiest way to generate the control input signal is electrically, using solenoid valves. Different opening and closing times can be set using throttle valves.

Double acting pneumatic actuators

The shut-off damper is opened and closed with compressed air. For this purpose, the actuator has two tube connections. Compressed air is applied to one tube connection while the other connection remains open such that the air can escape from the corresponding chamber of the actuator. For the other direction of rotation, the process is reversed.
