• Maximum Working Pressure: 300 psi
• Maximum Temperature Rating: 180°F (LPV Option)
• Notable Certifications: ASSE 1003; IAPMO; CSA; NSF 61
• Connection Type: Single Union, FNPT

Other Related Variants:

• Model 600XL (Standard): Other standard 600XL models

Materials:

• Body & Access Covers: Low Lead Cast Bronze ASTM B 584 / Low Lead Brass
• Fasteners: Stainless Steel, 300 Series
• Stem & Plunger: Low Lead Cast Bronze ASTM B 584 / Low Lead Brass
• Elastomers: Buna Nitrile (FDA Approved) / EPDM (FDA Approved)
• Seat: Stainless Steel, 300 Series
• Strainer Screen: Stainless Steel, 300 Series
• Cap Gaskets: Natural Vulcanized Fibre / Acetal (Delrin™)

Typical Installation:

Local codes shall govern installation requirements. Unless otherwise specified, the assembly shall be mounted in accordance with the latest edition of the Uniform Plumbing Code. The Model 600XL may be installed in any position. If installed in a pit, vault or inside application, specify the "SC" sealed cage option. Multiple installations are recommended for wide demand variations or where the desired pressure reduction is more than 4 to 1 (i.e.: 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. Do not bottom adjustment bolt on bell housing.

Standards Compliance:

ASSE Listed 1003; IAPMO Listed; CSA Certified; City of Los Angeles Approved; NSF/ANSI/CAN 61

Features & Benefits:

• Thermal Expansion Protection: Integral bypass check valve prevents excessive system pressure buildup caused by thermal expansion, protecting the plumbing system.
• Balanced Piston Design: Provides smooth and responsive reaction to changes in system flow demand while protecting from inlet pressure changes for consistent pressure regulation.
• Integrated Strainer: Built-in strainer makes the Zurn 34-600XLLPV ideal for systems requiring frequent cleaning due to sediment and debris, reducing maintenance requirements.
• Flexible Installation Options: Can be installed in any position with separate access covers for plunger and strainer screen, simplifying maintenance and adjustment procedures.

FAQ

Q: What is the pressure reduction range for the Zurn 34-600XLLPV with LPV option?

A: The LPV option provides a spring range of 10 psi to 35 psi, factory preset at 20 psi, with a maximum temperature rating of 180°F.

Q: Can this valve be installed in outdoor pit or vault applications?

A: Yes, the valve can be installed in any position. For pit, vault, or inside applications, specify the "SC" sealed cage option for optimal performance and protection.

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

A: Multiple installations are recommended for pressure reductions exceeding a 4:1 ratio. Always use a downstream pressure gauge to verify correct pressure settings when adjusting the valve.
