Burnham Boiler 822711 3/4 Ton R404A/R507/R502 Medium Temp TXV, Angle Body

Description

Engineered for reliable refrigerant metering in commercial and light-commercial refrigeration systems, the Burnham Boiler 822711 is a medium-temperature thermal expansion valve (TXV) built to deliver consistent superheat control and long-term system performance. Compatible with R404A, R507, and R502 refrigerants, this internally equalized angle body valve simplifies installation while reducing system complexity.

Key Features

• Internally equalized design provides accurate superheat control without requiring an external equalizer line
• Medium temperature charge optimized for R404A, R507, and R502 refrigerant systems
• Angle body configuration enables flexible installation in tight or space-constrained applications
• 3/4 Ton rated capacity matched to small commercial and light-duty refrigeration loads
• 30″ capillary tube allows remote bulb placement for easy field installation
• SAE flare connections deliver leak-free, tool-ready assembly

Application

The 822711 is ideally suited for medium-temperature refrigeration equipment including walk-in coolers, display cases, and reach-in refrigerators operating on R404A, R507, or R502 refrigerant circuits. The angle body design simplifies installation where straight-through valve placement is impractical, while the internally equalized construction eliminates the external equalizer line — reducing system complexity and minimizing potential leak points.
