The SAV Plus™ is a heavy-duty position control valve that maintains a valve’s position based on a desired % output set point. It is designed to work in applications where the control of a process variable (PV) is accomplished using an independent sensor. Perfect for controlling Dew-point, Carbon Potential, etc.

The SAV Plus™ incorporates a standard Waukee Flo-Meter scaled to the application requirements and an electronic control valve that modulates flow based on an external signal from a control system. The external signal can be 4-20mA or may be delivered using digital communications.

  • Large LCD display provides vital information such as Valve position, Alarms, and diagnostic messages
  • Simple and intuitive programming menus
  • Field programmable engineering units
  • Standard Modbus TCP for easy integration with control systems
  • Manual actuation of valve possible
  • Easy to install
  • Built-in Web Server for remote access to device
  • Calibration in state-of-art ISO/IEC 17025:2005 accredited laboratory
  • Visual flow indication



  • For applications requiring electronic measurement of flow rate, upgrade to our Valve-Tronic Plus™ control valve which includes a flow sensor.
