Electronicaly controlled electromotive rate valve is designed for accurate feed of gas chlorine into the water.

 

  • 4 –20 mA proportional control input
  • V-notch precision rate valve
  • Modbus communication
  • High quality stepper motor
  • 5-point valve calibration
  • Led indication of the valve position
  • Manual or automatic control
 
GENERAL

Electronically controlled motor driven rate valve is designed for accurate feed of chlorine gas and other technical gases into water.

Made of high quality materials,resistant to high concentrationsof aggressive gases. Built-in seals are made of fluorinated hydrocarbons (FKM, PTFE), materials resistant to aggressive gases.

Manual control over integrated keyboard and full manual control over top handwheel; automatic control over current or voltage input and via digital communications.

Fault signal is visible through the user interface or via a digital output.

The non-linearity of the valve can be repaired  by software in five points.

Built-in security feature: In case of power loss the valve has a battery backup that closes or opens the valve. 

It also allows completely mechanical handling in case of power loss.

ELECTRICAL DATA

Analog input:

Current input

0 .. 4 – 20 mA ( internal resistance 100 Ω )

Voltage input

0 .. 2 – 10 V (internal resistance 100 KΩ )

Function:

Valve position= Analog  input value


Digital input:

Electrical function:Internal supply digital input

Maximum voltage: 24 V

Maximum current: 1 mA

Signal “1” at 10 V

Signal “0” at 4 V

Function:

Contact normally closed =in operation

Contact open = Valve failure
