Zurn Wilkins 2" 500XL HLR Pressure Reducing Valve, Lead-Free - 2-500XLHLR

Zurn Wilkins 2" 500XL HLR Pressure Reducing Valve, Lead-Free - 2-500XLHLR

The Wilkins 2" 500XL HLR pressure reducing valve is a lead-free, high-flow regulator designed for reliable commercial, industrial, and irrigation pressure control. The high-flow capacity and low fall-off characteristics make it ideal for systems requiring stable downstream pressure across varying demand.

Suitable for potable water lines, commercial irrigation, and industrial installations, the 2-500XLHLR is offered with comprehensive documentation including specification sheets and installation and maintenance instructions. Proper installation requires downstream pressure verification with a gauge; consult the manufacturer spec sheet for dimensional, connection, and repair kit details.

Features

• High/Low Range (HLR): Adjustable 10–125 PSI for wide pressure control needs.
• Lead-Free Construction: Meets potable water requirements where lead-free components are required.
• High Flow, Low Fall-Off: Engineered to maintain downstream pressure with minimal drop-off at increased flow rates.
• Compact, Durable Design: Short lay length with a threaded bell for easy cartridge access and corrosion resistance.
• Integral Bypass: Direct-acting bypass prevents excessive pressure buildup from thermal expansion.
• Serviceable: Repair parts and cartridge kits available for routine maintenance and field service.

What our Experts Think

• Wide operating range (HLR design): Handles approximately 10–125 PSI adjustment range, making it flexible for variable incoming pressure conditions in municipal, commercial, and irrigation systems.
• High-flow performance: Built for systems that demand consistent pressure delivery with minimal fall-off, even under heavy simultaneous water use.
• Commercial/industrial durability: Heavy-duty bronze body construction with corrosion-resistant internal components designed for long service life in harsh environments.
• Lead-free potable water compliant: Meets modern plumbing code requirements for safe drinking water applications.
• Stable pressure regulation: Engineered balanced piston design helps maintain steady outlet pressure despite fluctuations in inlet supply.
• Service-friendly architecture: Threaded bell and cartridge-style internals simplify maintenance and reduce downtime in the field.
• Compact commercial footprint: Designed to fit tighter mechanical spaces while still delivering full 2" high-capacity performance.

Q&A

Q: What is the Zurn Wilkins 2-500XLHLR used for?
A: A 2" lead-free high-capacity pressure reducing valve (PRV) designed to lower and stabilize incoming water pressure in commercial, industrial, and irrigation systems.

Q: What does “HLR” mean?
A: “HLR” stands for High/Low Range, allowing a wide adjustable outlet pressure range (typically about 10–125 PSI) for flexible system tuning.

Q: Is it suitable for potable water systems?
A: Yes. It is lead-free compliant and certified for potable water use under NSF/ANSI 61 and ASSE standards for pressure regulation applications.

Q: What makes the 500XL series different from standard PRVs?
A: It is designed for high flow with minimal pressure drop (“low fall-off”), maintaining stable downstream pressure even under heavy demand.

Q: What type of applications is it used in?
A: Large residential, commercial buildings, irrigation systems, and industrial water distribution lines where consistent pressure control is critical.

Q: What are its construction features?
A: Lead-free bronze body, balanced piston design, and a serviceable cartridge-style internal assembly for easier maintenance.

Q: What are its pressure and performance characteristics?
A: Adjustable outlet pressure (HLR range), typically handling up to ~175 PSI inlet pressure with strong flow capacity and stable regulation under variable demand.

Maintenance Tips

• Check outlet pressure annually to ensure stable regulation and correct setpoint performance.
• Inspect for leaks, pressure creep, or fluctuating downstream pressure, especially after system changes.
• Clean the integral strainer and internal components periodically to remove sediment and debris buildup.
• Flush the supply line before servicing to prevent contaminants entering the valve body.
• Use a downstream pressure gauge when adjusting settings for accuracy and system protection.
• Replace worn cartridges, seals, or parts using genuine Zurn Wilkins repair kits only.
• After maintenance, verify pressure settings and check for leaks before returning the system to service.
