Model 22WC Well Commander Series (one valve/one well)

Model 22WC Well Commander Series (one valve/one well)

The model 22WC “Well Commander System” provides control of well / aquifer levels to prevent over pumping. The system consists of one diaphragm actuated control valve, installed on the discharge of a well, and an electronic multi-stage controller. Combining the advantages of simplicity and line pressure operation with the features of electronic control, the system is able to monitor and control the variables of the well and constant speed pump via a single controller interface while providing remote access.


  • Primary control of well depth via level/depth transducer*
  • Secondary control of: Output flow rate via flow meter transducer* and Valve discharge pressure via pressure transducer*
  • Allows for frequent set point change of control type selected
  • The controls for the well can be operated in either manual or automatic mode
  • Model 115-36 digital control valve with dual solenoid and ‘hydraulic’ reverse flow check
  • The valve opens slowly on pump start and closes slowly prior to pump shutdown
  • User-friendly color touch screen operation
  • Scheduling for the control of the valve (time, day of week, flow limiting, process variables)
  • Volume totalizer for valve output (when used with a flow meter)
  • Remote operation and monitoring of the valve and discrete pump run conditions
  • Remote set point by digital SCADA access
  • Extreme stability over wide range of operation
  • Wider range of flow control than standard hydraulic systems
  • Full function PID controller
  • RS232/RS485 communications (CANBUS, MODBUS)
  • 100-260Vac 50-60Hz with 24/12 VDC (optional)
  • Optional:
    • Analog Output (4-20mA)
    • Intranet monitoring control and e-mailing
    • Pump discharge pressure (replaces valve discharge pressure)
    • Manual override of valve operation
    • Valve position transmitter (not required for valve operation)
    • Consult factory for other options and control features as required

*Only one process variable is in control at any given time but they may all be monitored simultaneously. Sensors/transducers are user supplied.
