The 600XL Pressure Reducing Valve handles sandy, debris-laden water systems for high-flow capacity in residential, commercial, and new construction applications. It meets compliance with universal plumbing code. The stainless steel strainer includes a standard 20 mesh configuration and separate-access cover for simplified cleaning, while the bronze threaded bell provides superior corrosion-resistance and speeds access to the internals – together, cutting labor time up to 50%. Internal components of the 600XL utilize a balanced design, providing accurate downstream pressure without consideration of the incoming pressure.
- Fiber union gasket ensures fast installation
- Durable construction ensures low maintenance and lifecycle costs
- Inlet pressure changes with balanced design features to protect the system
- Stainless steel strainer screen features single-cap removal
- Threaded bell provides easier access than bolted on bells
- Low-lead law compliant
Application Zurn Wilkins model 600XL is designed for installation on potable water lines to reduce high inlet pressure to a 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 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.
Standards Compliance
• ASSE® Listed 1003
• IAPMO® Listed
• CSA® Certified
• City of Los Angeles Approved
• Meets the requirements of NSF/ANSI/CAN 61
Local codes shall govern installation requirements. Unless otherwise specified, the assembly shall be mounted in accordance 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.
