Introduction

he 220G Series provides a full family of brass valves are designed specifically to meet

the challenging needs of today’s golf course irrigation systems. Featuring precision

pressure regulation, the 220G Series brass 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 220G 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 220G 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 220G 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

accessible by grounds maintenance personnel and well clear of hardscape features,

cart paths and foot traffic areas.

Installation Guidelines • Note the flow direction arrow in the side of the valve body and install accordingly. Control Wire Gauge Size Common Wire Gauge Size • The valve can be installed at any angle without affecting operation. • Use direct-burial irrigation control wire for connection from the controller to valves. • Leave a 12" wire expansion loop at each valve location on long-run wire lengths. • Waterproof wire splice connectors are absolutely essential for proper electric control system operation.
