Typical Installation:

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 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). 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.

Standards Compliance:

ASSE Listed 1003; IAPMO Listed; CSA Certified; City of Los Angeles Approved; NSF/ANSI/CAN 61

Features & Benefits:

• Balanced Piston Design: Provides smooth and responsive operation to changes in system flow demand while protecting against inlet pressure fluctuations.
• Integral By-pass Check Valve: Prevents buildup of excessive system pressure caused by thermal expansion in closed water systems.
• Integrated Strainer: Built-in strainer with separate access cover allows for easy cleaning and maintenance in systems with sediment and debris.
• Versatile Installation: Can be installed in any position with sealed cage option available for pit, vault, or indoor applications.

FAQ

Q: Can the Zurn 2-600XLC be installed in any position?

A: Yes, the Zurn 2-600XLC may be installed in any position. If installed in a pit, vault, or inside application, specify the "SC" sealed cage option for optimal performance.

Q: What is the factory preset pressure for the Wilkins 2-600XLC?

A: The valve comes factory preset at 50 psi, with a standard reduced pressure range of 25 psi to 75 psi adjustable in the field.

Q: How do I properly adjust the downstream pressure on this valve?

A: Always use a pressure gauge downstream to verify the correct pressure setting when adjusting the valve. Do not bottom the adjustment bolt on the bell housing during adjustment.
