3.2 Function and mode of operation
By means of the pneumatic actuator pneumatic control signals are converted into a shearing movement. The
necessary reaction force is generated by the pressure springs on membrane plate.
In case of air failure the actuator is reset into the initial position through the spring force.
The operating mode of the drive, spring opens – air closes (SO) or air opens – spring closes (SC) is
achieved depending on the installation of the springs. For actuators already installed in systems the
operating mode can be changed with simple tools without additional parts.
