Typical Installation:

The Zurn 112-500XL3 is typically installed on commercial and industrial potable water lines where high inlet pressure needs to be reduced to a lower outlet pressure. The valve may be installed in any position and is suitable for commercial plumbing systems and industrial water lines. Multiple installations in series are required when the desired pressure reduction is more than 3 to 1 ratio.

Standards Compliance:

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

Features & Benefits:

• High Flow Performance: Patented integral venturi enables best-in-class flow performance for commercial and industrial applications.
