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 Zurn 212-500XL may be installed in any position. If installed in a pit, vault, or inside application, specify the "SC" sealed cage option. Multiple installations are recommended 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 (1/2" thru 2 1/2"); cUPC Listed (1/2" thru 2"); CSA Certified B356 (1/2" thru 2"); City of Los Angeles Approved (1/2" thru 2"); NSF/ANSI/CAN 61; NSF/ANSI/CAN 372

Features & Benefits:

• Integral By-Pass Check Valve: Prevents buildup of excessive system pressure caused by thermal expansion.
• Balanced Piston Design: Ensures smooth and responsive reaction to system flow demand changes while providing protection from inlet pressure fluctuations.
• High Flow Capacity: Most suitable for industrial water lines and commercial water systems requiring reliable pressure reduction.
• Accessible Maintenance: Assembly can be serviced without removing the body from the line, reducing downtime and installation costs.

FAQ

Q: Can the Wilkins 212-500XL be installed in any orientation?

A: Yes, the Model 500XL may be installed in any position. For pit, vault, or inside applications, use the "SC" sealed cage option.

Q: What pressure reduction ratio is recommended for the Zurn 212-500XL?

A: Multiple installations are recommended for wide demand variations or where the desired pressure reduction exceeds a 3:1 ratio (e.g., 150 psi inlet reduced to 50 psi outlet).

Q: How do I adjust the outlet pressure on this valve?

A: Use a downstream pressure gauge to verify correct pressure setting when adjusting. Do not bottom the adjustment bolt on the bell housing. The valve is factory preset at 50 psi with a range of 25-75 psi.
