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).

Standards Compliance:

ASSE® Listed 1003; IAPMO® Listed; CSA® Certified; City of Los Angeles Approved; NSF/ANSI/CAN 61; NSF/ANSI/CAN 372

Features & Benefits:

• High Inlet Pressure Capability: The Zurn 34-610XL 610XL option delivers 400 psi inlet rating with 75-125 psi reduced pressure range, factory set at 85 psi for demanding high-flow applications.
• Integral Strainer and Thermal Expansion Relief: Built-in 20 mesh stainless steel strainer with separate access cap simplifies maintenance while the integral by-pass check valve prevents excessive system pressure from thermal expansion.
• Balanced Piston Design: Ensures smooth, responsive pressure regulation during flow demand changes and protects against inlet pressure fluctuations for stable outlet pressure.
• Lead-Free Compliance: Constructed with low lead cast bronze body and stainless steel internals meeting NSF/ANSI/CAN 61 & 372 for safe potable water use.

FAQ

Q: Can the Wilkins 34-610XL be installed in any orientation?

A: Yes, the 34-610XL may be installed in any position including horizontal, vertical, or angled orientations to suit your installation requirements.

Q: What is the difference between the standard 600XL and the 610XL option?

A: The 610XL option increases the inlet pressure rating from 300 psi to 400 psi and adjusts the spring range from 25-75 psi (standard) to 75-125 psi, with factory setting at 85 psi instead of 50 psi.

Q: How do I access the strainer screen for cleaning?

A: The Zurn 34-610XL features a separate access cap for the integral strainer screen, allowing for easy removal and cleaning without disturbing the main valve assembly or downstream piping.
