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 Zurn 114-600XLC 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:

• Integrated By-pass Check Valve: Prevents buildup of excessive system pressure caused by thermal expansion, providing comprehensive protection.
• Balanced Piston Design: Enables smooth and responsive reaction to changes in system flow demand while providing protection from inlet pressure changes.
• Integral Strainer: Most suitable for systems requiring frequent cleaning due to sediment and debris, ensuring continuous optimal performance.
• Flexible Installation: Can be installed in any position, providing versatility for various applications and installation scenarios.

FAQ

Q: What is the factory preset pressure setting for the Wilkins 114-600XLC?

A: The valve is factory preset at 50 psi with a standard pressure range of 25 psi to 75 psi. The pressure can be adjusted using the adjustment bolt with a downstream pressure gauge.

Q: Can the Zurn 114-600XLC be installed in pits or vaults?

A: Yes, the valve may be installed in any position. However, if installed in a pit, vault, or inside application, you must specify the "SC" sealed cage option for proper protection.

Q: What is the maximum recommended pressure reduction ratio?

A: Multiple valve installations are recommended where the desired pressure reduction is more than 4 to 1 (for example, 200 psi inlet reduced to 50 psi outlet) to ensure optimal performance and valve longevity.
