What types of valves are compatible with Guardian?


The Guardian Valve Controller will work with most metal quarter-turn ball valves from 1/2" to 1".  See the example valve below - a handle similar to this one is required for the Valve Controller to grasp the valve and turn it.  

In addition, the valve must be operable by hand prior to installation, and some clearance is necessary for the Valve Controller to fit in the installation:

  • 4.5” before and after valve (measured from valve’s center) without elbows or other fittings for the Valve Controller's clamps
  • 5” clearance above the valve nut
  • Power outlet within 10’ of valve (or extension cord)
