Typical Installation:

Local codes shall govern installation requirements. 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 Wilkins 2-500XLHRYSBR 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 3 to 1. Install in horizontal orientation with strainer upstream protection. The strainer allows easy maintenance and debris removal. Suitable for potable water pressure regulation where inlet filtration is required.

Features & Benefits:

• Integral By-Pass Check Valve: Prevents buildup of excessive system pressure caused by thermal expansion, providing comprehensive protection in a single assembly.
• Balanced Piston Design: Enables smooth and responsive reaction to system flow demand changes while providing protection from inlet pressure fluctuations.
• Inlet Y Strainer (YSBR Option): Lead-free bronze Y strainer provides upstream debris protection with easy maintenance and removal capability.
• High Pressure Spring Range (HR Option): Factory set at 85 psi with adjustable range from 75 psi to 125 psi for demanding commercial applications.

FAQ

Q: What is the pressure range for the Wilkins 2-500XLHRYSBR with HR option?

A: The HR option provides a spring range of 75 psi to 125 psi and comes factory set at 85 psi, making it ideal for applications requiring higher outlet pressures than the standard model.

Q: Can the 2-500XLHRYSBR be installed vertically?

A: Yes, the Model 500XL may be installed in any position including vertical, horizontal, or at an angle. However, install with sufficient side clearance for testing and maintenance access.

Q: How do I maintain the Y strainer on this pressure reducing valve?

A: The lead-free bronze Y strainer allows for easy maintenance and debris removal. The strainer should be installed upstream to protect the valve and can be accessed for cleaning without removing the entire valve assembly from the line.
