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.
