Typical Installation:
The Zurn 34-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 (0.25% Max Weighted Average Lead Content)
Features & Benefits:
- Integral By-Pass Check Valve: Prevents buildup of excessive system pressure caused by thermal expansion, protecting plumbing systems and appliances.
- Balance Piston Design: Provides smooth and responsive reaction to changes in system flow demand while offering protection from inlet pressure changes.
- Integral Strainer: Built-in stainless steel strainer allows for frequent cleaning of sediment and debris without additional components.
- Corrosion-Resistant Construction: Sealed cage washer and stainless steel adjustment components enable reliable performance in all applications including below-ground pit installations.
FAQ
Q: Can the Wilkins 34-NR3XL be installed in any position?
A: Yes, the Model NR3XL may be installed in any position. However, sufficient side clearance must be provided for testing and maintenance access.
Q: What is the factory preset pressure for the Zurn 34-NR3XL?
A: The valve is factory preset to 50 psi and has an adjustable reduced pressure range of 15 to 75 psi. A downstream pressure gauge must always be used when adjusting the pressure setting.
Q: What is the maximum pressure reduction ratio recommended for this valve?
A: The NR3XL is recommended for pressure reductions not exceeding a 4:1 ratio. For greater pressure reductions (e.g., 200 psi inlet to 50 psi outlet), multiple installations are recommended.
NOTICE: Do not use with water that is unsafe or of unknown quality without adequate disinfection either before or after the system.
