P220G Series Plastic Valves
Installation and Operating Instructions
Introduction
The P220G Series provides a full family of plastic valves are designed specifically to meet
the challenging needs of today’s golf course irrigation systems. Featuring precision pressure
regulation, the P220G Series valve delivers the optimum pressure and flow to every sprinkler
on the zone, ensuring maximum uniformity of the water to the turf.
The EZ-Reg pressure regulating system, a standard feature on all P220G valves, provides
consistant operating pressure. From low-pressure/flow applications of drip irrigation, to the
high-pressure/flow requirements of high-volume sprinklers, the EZ-Reg adjusts easily with
the micro-adjust dial and indicator, to provided constant downstream pressure 5–100 psi.
Also standard on the P220G series, is the heavy-duty SpikeGuard™ solenoid. Providing
20,000-volt lightning protection – the SpikeGuard solenoid has proven to minimize down
time and service costs, even in the severe lightning-prone regions.
Note: The P220G valve should be installed below grade in a valve box or vault to provide
service access and vandal resistance. The valve installation site should be readily accessi-
ble by grounds maintenance personnel and well clear of hardscape features, cart paths
and foot traffic areas.
