KY II type governor unit


  • This governor unit is most suitable for dedicated small-flow control.

  • An integrated structure of two-way governor, shut-off valve and angle type filter saves installation space.

  • Unitization reduces cost and work hours.
    (Please use our dedicated template to study pre-installation piping.)

  • Optionally, shut-off valve can be linked with fire and earthquake alarms, thus enabling the governor unit to operate as a multi-purpose function device (WS-TS type).
