Motor-Driven Control Valve for Chlorine Gas DULCO®Vaq
Capacity: 12 g/h to 15 kg/h
The motorised control valve for chlorine gas DULCO®Vaq type PM 3531 ensures precise electronically controlled metering of the chlorine gas flow. The linear control characteristic is guaranteed by an externally controlled step motor.
Chlorine gas metering, precisely regulated
The DULCO®Vaq motorised control valve is fitted in the vacuum system between the vacuum controller and injector. The chlorine gas flow is therefore automatically adjusted. A step motor thus controls the ultra-precise V-nozzle, which results in a linear control characteristic. Control is either provided by manual adjustment on the keyboard of the device, via external signals, such as 0/4-20 mA, 0/2-10 V or Modbus. Opening and operating statuses are signalled externally by analogue and digital outputs and by coloured LEDs on the device. In the event of power failure, the valve closes automatically, although mechanical manual operation is possible.
