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 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.
