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:

• High-Range Pressure Control: The Zurn 2-600XLHR features HR option with 75 psi to 125 psi spring range, factory set at 85 psi for demanding applications requiring elevated outlet pressure.
• Thermal Expansion Protection: Integral by-pass check valve prevents buildup of excessive system pressure caused by thermal expansion, protecting water heaters and plumbing fixtures.
• Integrated Debris Filtration: Built-in 20 mesh strainer screen with easy-access cover allows frequent cleaning to maintain optimal performance in systems with sediment and debris.
• Balanced Piston Design: Smooth and responsive pressure regulation reacts efficiently to system flow demand changes while providing protection from inlet pressure fluctuations.

FAQ

Q: Can the Wilkins 2-600XLHR be installed in any orientation?

A: Yes, the Model 600XL may be installed in any position. For pit, vault, or inside installations, specify the "SC" sealed cage option for additional protection.

Q: What pressure reduction ratio is recommended for this valve?

A: Multiple installations are recommended for wide demand variations or where the desired pressure reduction exceeds a 4:1 ratio (e.g., 200 psi inlet reduced to 50 psi outlet).

Q: How do I adjust the outlet pressure on the Zurn 2-600XLHR?

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