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

Features & Benefits:

• Integral Strainer Design: Built-in strainer removes sediment and debris, making the Zurn 1-NR3XLP most suitable for systems requiring frequent cleaning without additional components.
• Thermal Expansion Protection: Direct acting integral by-pass design prevents buildup of excessive system pressure caused by thermal expansion, protecting your plumbing system.
• Balance Piston Technology: Smooth and responsive reaction to changes in system flow demand while providing protection from inlet pressure changes.
• Easy Maintenance Access: Assembly accessible for maintenance without removing the device from the line; sealed cage washer and stainless steel adjustment components improve corrosion resistance for all applications including below-ground pit installation.
