Red-white Valve 9519 Dzr Brass Static Balancing Valve

Product Description

The RED-WHITE VALVE 9519 is a fixed orifice static balancing valve constructed from DZR (dezincification-resistant) brass, designed for hydronic heating and cooling distribution systems. The fixed orifice design maintains a preset flow balance across the system without requiring manual adjustment after commissioning. At 0.5 inches with solder end connections and a 300 WOG pressure rating, this valve is built for reliable, long-term performance in closed-loop hydronic circuits. Licensed plumbers and hydronic system technicians are the primary installers of this type of component.

The 9519 is suited for residential and light commercial hydronic systems where consistent flow balancing is required across multiple zones or terminal units. Its solder end connections make it compatible with standard copper tubing installations. The fixed orifice configuration simplifies system commissioning by eliminating the need for field flow adjustments at each balancing point, making it a practical choice for new construction and retrofit hydronic piping layouts.

Key Features

• DZR brass construction resists dezincification in aggressive water conditions
• Fixed orifice design provides static flow balance without field adjustment
300 WOG pressure rating suits standard hydronic system operating conditions
• 0.5 inch solder end connections integrate directly with copper tubing
• Compact form factor fits into tight mechanical room and chase installations

Compatibility

Designed as an OEM-style replacement or new-installation component for standard residential and light commercial hydronic balancing applications using 0.5 inch copper solder-end piping.

Installation Notes

Installation should be performed by a licensed plumber or qualified hydronic system technician in accordance with applicable local plumbing codes and the International Plumbing Code (IPC). Shut down and depressurize the hydronic system completely before cutting into any existing piping. Use appropriate soldering flux and lead-free solder when making sweat connections on potable or closed-loop systems. Do not exceed the rated 300 WOG working pressure during system pressure testing.
