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 Model 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).

Standards Compliance:

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

Features & Benefits:

• High Flow Capacity: Designed specifically for industrial water lines and commercial water systems with demanding flow requirements.
• Thermal Expansion Protection: Direct acting integral by-pass design prevents buildup of excessive system pressure caused by thermal expansion.
• Balanced Piston Design: Provides smooth and responsive reaction to changes in system flow demand while protecting from inlet pressure fluctuations.
• Flexible Installation: Can be installed in any position, with sealed cage option available for pit, vault, or inside installations.
