Typical Installation:

The Model NR3XL may be installed in any position. The assembly 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 (ie: 200 psi inlet reduced to 50 psi outlet). Anytime a reducing valve is adjusted, a pressure gauge must be used downstream to verify correct pressure setting.

Standards Compliance:

ASSE Listed 1003; IAPMO Listed; CSA Certified; NSF/ANSI/CAN 61

Features & Benefits:

• Integral By-Pass Check Design: Prevents buildup of excessive system pressure caused by thermal expansion, providing comprehensive system protection.
• Balance Piston Design: Enables smooth and responsive reaction to changes in system flow demand while providing protection from inlet pressure changes.
• Integral Strainer: Makes the Zurn 2-NR3XL ideal for systems requiring frequent cleaning of sediment and debris without additional components.
• Corrosion Resistant Construction: Sealed cage washer and stainless steel adjustment bolt and nut improve corrosion resistance for all applications including below-ground pit installation.

FAQ

Q: Can the Zurn 2-NR3XL be installed in any position?

A: Yes, the Model NR3XL may be installed in any position. Ensure sufficient side clearance is provided for testing and maintenance.

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

A: Multiple installations are recommended for wide demand variations or where the desired pressure reduction is more than 4 to 1 (ie: 200 psi inlet reduced to 50 psi outlet).

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

A: Anytime a reducing valve is adjusted, a pressure gauge must be used downstream to verify correct pressure setting. Do not bottom adjustment bolt on bell housing.
