ZURN 600XL Water Pressure Reducing Valve
Application
Zurn Wilkins model 600XL is designed for installation on potable water lines to reduce high inlet pressure to lower outlet pressure. The integral strainer makes this device most suitable for residential and commercial water systems requiring frequent cleaning because of sediment and debris. The direct-acting integral by-pass design prevents the 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
“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 accor-dance with the latest
edition of the Uniform Plumbing Code. The Model 600XL may be installed in any
position. If installed in a pit, vault or inside application, specify the “SC”
sealed cage option. Multiple installations are recommend 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 correct pressure
setting. Do not bottom adjustment bolt on bell
housing.
Specifications
The Pressure Reducing Valve shall be certified to NSF/ANSI/CAN 61, consist of a low lead bronze body and bronze bell hous-ing, shall have separate access covers for the plunger and strainer screen and shall have a bolt to adjust the downstream pressure. The Pressure Reducing Valve shall be of the balanced piston design and shall reduce pressure in both flow and no-flow conditions. The bronze bell housing and access caps shall be threaded to the body and shall not require the use of ferrous screws. The Pressure Reducing Valve shall be a ZURN WILKINS Model 600XL.
