Master Valve (P/MV) Operation per zone
Brief Summary
A master valve is a normally closed valve installed at the supply point of the main line that
opens only when the automatic system is activated. Zone valves are the individual valves
that operate a group of sprinklers or drip emitters. Hydrawise controllers support 6 - 54
zone valves, depending on the model. Typically one zone valve is turned on at a time and
controls the irrigation in a specific area of your garden. Whenever one of the irrigation zone
valves is told to open by the controller, the controller also signals the master valve to open.
The purpose of the master valve is to shut off the water to the irrigation system when none
of the zone valves are operating.
