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 Zurn 114-500XL 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 3 to 1 (i.e.: 150 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.

Standards Compliance:

ASSE Listed 1003; cUPC Listed; CSA Certified B356; City of Los Angeles Approved; NSF/ANSI/CAN 61 and 372

Features & Benefits:

• High Flow Capacity: Ideal for industrial water lines and commercial water systems with balanced piston design for smooth, responsive operation.
• Integral By-pass Check Valve: Prevents buildup of excessive system pressure caused by thermal expansion, providing comprehensive pressure control.
• Low Lead Compliance: Meets NSF/ANSI/CAN 61 and 372 standards with less than 0.25% weighted average lead content for safe potable water applications.
• Flexible Installation: Can be installed in any position with single union connection for easy maintenance without removing body from line.

FAQ

Q: What is the factory preset pressure for the Wilkins 114-500XL?

A: The Wilkins 114-500XL comes factory preset at 50 psi with an adjustable reduced pressure range of 25 psi to 75 psi.

Q: Can this valve be installed in any orientation?

A: Yes, the Model 500XL may be installed in any position. However, if installed in a pit, vault, or inside application, the "SC" sealed cage option should be specified.

Q: What is the maximum recommended pressure reduction ratio?

A: Multiple installations are recommended where the desired pressure reduction is more than 3 to 1 (for example: 150 psi inlet reduced to 50 psi outlet) to ensure optimal performance.
