Typical Installation:

The Zurn 2-NR3XLDU may be installed in any position and shall be installed with sufficient side clearance for testing and maintenance. Multiple installations are recommended for wide demand variations or where the desired pressure reduction is more than 4 to 1 ratio. A pressure gauge must be used downstream to verify correct pressure setting when adjusting the valve. Do not bottom adjustment bolt on bell housing. Suitable for outdoor installation, residential and commercial water systems.

Standards Compliance:

ASSE 1003 Listed; IAPMO Listed; CSA Certified; NSF/ANSI/CAN 61 (0.25% Max Lead Content)

Features & Benefits:

• Integral By-Pass Check Valve: Prevents buildup of excessive system pressure caused by thermal expansion, protecting the plumbing system.
• Built-In Strainer: Ideal for systems requiring frequent cleaning of sediment and debris, reducing maintenance requirements.
• Balanced Piston Design: Provides smooth and responsive reaction to flow demand changes while protecting against inlet pressure fluctuations.
• Lead-Free Construction: Meets NSF/ANSI/CAN 61 with 0.25% max lead content, safe for potable water applications.

FAQ

Q: Can the Wilkins 2-NR3XLDU be installed in any orientation?

A: Yes, the Zurn 2-NR3XLDU may be installed in any position. However, ensure sufficient side clearance is provided for testing and maintenance access.

Q: What pressure reduction ratio is recommended for this valve?

A: Multiple installations are recommended for pressure reductions exceeding a 4:1 ratio. For example, reducing 200 psi inlet to 50 psi outlet should use staged valves.

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

A: Always use a downstream pressure gauge when adjusting the valve. The factory preset is 50 psi, adjustable within the 25-75 psi range. Do not bottom the adjustment bolt on the bell housing.
