Typical Installation:

The Zurn 34-20XLDULU may be installed in any position on potable water service lines where pressure reduction is required. Local codes shall govern installation requirements. 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). The valve is ideal for residential and water systems that require frequent cleaning of sediment and debris, and can be used in both indoor and outdoor installations.

 

Standards Compliance:

ASSE Listed 1003; cUPC Listed; CSA Certified B356; NSF/ANSI/CAN 61; NSF/ANSI/CAN 372 (lead-free)

 

Features & Benefits:

  • Integral Strainer Design: Built-in strainer filters sediment and debris, making it ideal for residential and water 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 the water system.
  • Simplified Installation: Two integral FNPT connections (no unions) minimize leak points and simplify piping connections, ideal for retrofit and tight spaces.
  • Balanced Stem Performance: Balanced stem design enables smooth and responsive reaction to changes in system flow demand while providing protection from inlet pressure changes.

 

FAQ

 

Q: What is the factory preset pressure setting for the Wilkins 34-20XLDULU?

A: The Zurn 34-20XLDULU comes factory preset at 50 psi, with an adjustable reduced pressure range of 25 to 75 psi. Always use a pressure gauge downstream when adjusting to verify correct pressure setting.

Q: Can the Model 20XLDULU be installed in any orientation?

A: Yes, the Model 20XL may be installed in any position. Ensure sufficient side clearance is provided for testing and maintenance access.

Q: What makes this valve lead-free compliant?

A: The valve meets NSF/ANSI/CAN 372 lead-free requirements with a maximum 0.25% weighted average lead content in wetted components, making it suitable for potable water applications where lead-free valves are required.
