ZURN 500XLFCBP Manual

Application
Zurn Wilkins model 500XLFCBP is designed for installation
on potable water lines to reduce high inlet pressure to a lower
outlet pressure. The high flow capacity makes this device
most suitable for industrial water lines and commercial water
systems. The balanced piston design enables the regulator
to react in a smooth and responsive manner to changes in
system flow demand, while at the same time, providing pro-
tection from inlet pressure changes. Body is drilled, tapped
and plugged to accept low flow by-pass (Model 34-NR3XL-
HRSCDUBPK).
