5 PRODUCT DESCRIPTION
5.1 Intended use
The motor valve Type 3280 and 3285 is designed for controlling the flow rate of liquid and gaseous media. Only
clean, liquid or gaseous medium, which does not react with the bodies and sealing materials, may be controlled.
NOTE!
Unsuitable medium will damage the body and the seals.
Unsuitable medium may damage the body and the seals.
• Use suitable medium only.
• Check chemical compatibility in individual cases.
5.2 Properties
The regulation of the flow or switching of the valve is regulated with the aid of a stepper motor actuator which is
controlled by the integrated electronic control system. Therefore, no external motor control is required for step control.
Basic functions of the control electronics:
• Control of the valve opening by processing the external set-point values
• Output of the valve states via the LED display
• Position detection after power failure
- if power fails, the current position of the valve is retained
- when power is restored, the internal control electronics automatically detects it’s current position
• Reduction in the energy consumption
- The valve is designed to hold its position without the active use of the motor. As soon as the desired position
is achieved, motor is turned off and the valve uses only fraction of power required to move the valve.
