220
Series Brass Valves
Installation Instructions
Introduction
Built on proven technologies and components, the Toro 220 Series brass
valves are tough, have excellent performance and are extremely reliable.
A self-flushing, clog-resistant, stainless-steel filter for dirty water conditions
assures years of trouble-free performance.
In commercial installations, it is advantageous to install the valves in a
valve box. This enables the valve to be located, accessed and maintained
easily. The use of clean aggregate in the the bottom of the box, and
keeping valve box locations away from structures, potential hardscaping
features (such as sidewalks) and large planting locations is recommended.
Additionally, valve box locations generally should be in shrub beds and at
right angles to structure locations. If the valves are installed below grade
without a valve box, access to the top of the valve should be provided using
a section of 4" PVC pipe and a Toro Valve Cover (Part No. 850-00) installed
directly over each valve.
