Features
The ZW3 is intended for any application where “through the wall” water control is desired.
Primarily intended for irrigation applications, the ZW3 valve provides outdoor access to control an
indoor water supply via a vandal resistant valve key. The ZW3 can eliminate scheduling hassles
and speed up the winterization process. Some applications may include system winterizing,
system repairs or system isolation.
