    Elastomer seal Control cone Body Figure 1: Electromotive seat valve Type 3280 5.3.2 electromotive disk valve Type 3285 The disk valve consists of a stepper motor with gearbox which transfers the rotational torque to the actuator shaft via coupling. The actuator shaft has control/shut-off disc attached to it. A fixed disk with a mouth attached to the body is used as a valve seat.

  • Page 11: Device Versions

    5.4.1 electric control The motor valves 3280 and 3285 feature an electromotive actuator with an electric control. The device version is stated on the type label: G means on-off, 0 resp. H means control valve, C means positioner and D stands for process controller.
  • Page 12 Type 3280, 3285 Productdescription Both valve end positions are indicated by the LED status. Moreover, the position actual value recorded using the position measuring system is output via the M12 circular plug-in connector. It is possible to communicate with the device digitally via CANopen* or büS**.
  • Page 13 Type 3280, 3285 Productdescription The process controller is integrated in a control circuit. The position set-point value of the valve is calculated from the process set-point value and the process actual value using the control parameters (PID controller). The process set-point value can be specified by an external signal.
