Toro 220G Series Installation And Operating Instructions

Introduction
The 220G Series valve offers two electrical activation types:
AC powered and DC powered.
For satellite systems, the 24 VAC Spike Guard solenoid provides 20,000 volt
lightning protection to minimize down time and service costs. Moreover, it
draws less than half the wattage of traditional solenoids for a lower long-term
cost of ownership.
For GDC 2-wire systems, a DC-latching solenoid reduces the system wire load
to lower initial system cost. It is activated by a momentary pulse "on" and "off",
meaning there is no continuous power draw, providing a lower long-term cost
of ownership.
The 220G brass valve adjusts easily with the micro-adjust dial and indicator to
provided constant downstream pressure between 5-100 psi (,34-6,9 bar).
Note: The 220G valve should be installed below grade in a valve box or vault
(see opposite page) 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.
