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
r
egulation, 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.
