Hunter PGJ Rotor - Use PGJ on the Same Zone with Other Rotors

Use PGJ on the Same Zone with Other Rotors
Now, when landscapes require smaller areas to be irrigated together with larger areas, the
PGJ and PGP rotors can be combined on one zone! As shown in this design, one valve can
control both the smaller area and the larger area and provide a uniform precipitation rate
over the entire landscape. Normally, two valves would have to be installed: one for a spray
zone and one for a rotor zone. So, less valves, piping, wire, and stations on the controller are
required!
