ZURN 500XL Water Pressure Reducing Valve with Integral By Pass Check
Valve
Application
Zurn Wilkins model 500XL 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 direct-acting integral by-pass design prevents
buildup of excessive system pressure caused by thermal expansion. 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 protection
from inlet pressure changes.

Flow Characteristics
MODEL 500XL 1/2″ THRU 3″ (STANDARD & METRIC)
“Flow curves are based on a 50 psi pressure differential
Typical Installation
Local codes shall govern installation requirements. Unless otherwise
specified, the assembly shall be mounted in accordance with the manufacturers’
instructions and the latest edition of the Uniform Plumbing Code. The assembly
shall be installed with sufficient side clearance for testing and maintenance.
The Model 500XL may be installed in any position. If installed in a pit,
vault, or inside the application, specify the “SC” sealed cage option.
Multiple installations are recommended for wide demand variations or where the
desired pressure reduction is more than 4 to 1 (i.e.: 200 psi inlet reduced to
50 psi outlet).
Caution: Anytime a reducing valve is adjusted, a pressure gauge must be
used downstream to verify the correct pressure setting. Do not bottom
adjustment bolt on the bell housing.
Specifications
The Pressure Reducing Valve shall be certified to NSF/ANSI/CAN 61, consisting of a low lead bronze body and bronze bell housing, a separate access cover for the plunger and a bolt to adjust the downstream pressure. The bronze bell housing and access cap shall be threaded to the body and shall not require the use of ferrous screws. The assembly shall be of the balanced piston design and shall reduce pressure in both flow and no-flow conditions. The assembly shall be accessible for maintenance without having to remove the body from the line. The Pressure Reducing Valve shall be a ZURN WILKINS Model 500XL.
