pneumatic and electro/pneumatic positioner
type 824 P / 824 E / 824 D


are analog controller, working on the principle of comparing forces and can be extended
with several additional modules.
The pneumatic nominal value input signal from a pneumatic controller or from an I/P-converter
module creates a force on the diaphragm, that is compared with the spring force on
the feedback shaft. The resulting difference of force is moving the gate valve, that is connecting
the gear with the supply air and thus controlling the movement of the valve.
The type 824 D controller has the protection class IP 65.
