Description
Product Overview
The Aprilaire 5773 is a heavy-duty externally equalized Thermal Expansion Valve (TXV) engineered for reliable refrigerant metering in medium-temperature commercial and industrial HVAC/R systems. Designed to handle an 11-ton capacity with R12 and R134A refrigerants, this valve delivers precise superheat control to maximize system efficiency and protect the compressor from liquid slugging.
Key Features
- Straight body design for straightforward inline installation
- 5/8″ x 7/8″ ODF sweat connections for secure, leak-free copper piping joints
- 5-foot capillary tube for flexible remote bulb placement on the suction line
- 11-ton R12/R134A refrigerant capacity for commercial-scale applications
- Medium temperature charge — optimized for medium-temperature refrigeration and comfort cooling applications
- External equalizer port compensates for evaporator pressure drop, ensuring accurate superheat control across the entire coil
- Model: HFES 11 MC 5FT 5/8 x 7/8 ODF S/T

Application
The external equalizer design makes the Aprilaire 5773 the preferred choice for evaporators with significant refrigerant-side pressure drop — common in multi-circuit coils and longer evaporators. The medium temperature charge suits applications such as commercial air conditioning, process cooling, and medium-temperature refrigeration cases where consistent superheat management is critical to system longevity and energy performance.
