Typical Installation:

Local codes shall govern installation requirements. The assembly shall be mounted in accordance with the manufacturer's 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 34-625XL3 may be installed in any position. Multiple installations in series are required when the desired pressure reduction is more than 3 to 1 (i.e. 150 psi inlet reduced to 50 psi outlet). A pressure gauge must be used downstream to verify correct pressure setting.

Standards Compliance:

ASSE Listed 1003; cUPC Listed; CSA Certified B356; NSF/ANSI/CAN 61 & 372

Features & Benefits:

• Best-in-Class Flow Performance: Patented integral venturi enables superior flow performance and easier sizing, providing ideal water pressure at higher flow rates.
• Enhanced Durability: Premium 300 series stainless steel internals provide enhanced corrosion resistance and lasting durability in demanding water systems.
• Easy Maintenance: Removable cartridge design and cost-effective repair kits significantly reduce maintenance time and costs without removing body from line.
• Balanced Piston Design: Reacts smoothly to system flow demand changes while providing protection from inlet pressure fluctuations in both flow and no-flow conditions.
