Description
The US Motors 5652 (Model HFES 1 HC 5FT 3/8 x 1/2 ODF S/T) is a precision-engineered Thermal Expansion Valve (TXV) designed for reliable refrigerant metering in medium-temperature refrigeration and air conditioning applications. Built to handle R22 and R407C refrigerants, this valve delivers consistent performance in 1-ton capacity systems where accurate superheat control is essential.
Featuring an externally equalized design, the valve compensates for pressure drop across the evaporator, ensuring stable superheat control even in longer or higher-resistance coil circuits. The straight-body configuration and sweat (ODF) connections make installation straightforward and leak-resistant. The included 5-foot capillary tube provides flexible bulb placement to suit a variety of evaporator configurations.

- Body style: Straight body
- Connection type: Sweat (ODF) — 3/8″ inlet x 1/2″ outlet
- Capillary tube length: 5 feet
- Equalization: Externally equalized for accurate superheat control in high-pressure-drop evaporators
- Model number: HFES 1 HC 5FT 3/8 x 1/2 ODF S/T
Applications
- Medium-temperature refrigeration systems
- Air conditioning systems using R22 or R407C refrigerant
- 1-ton evaporator coil circuits requiring precise superheat regulation
- Systems with multi-circuit or longer evaporator coils benefiting from external equalization
Why Choose the US Motors 5652 TXV?
The externally equalized design sets this valve apart from internally equalized alternatives by referencing evaporator outlet pressure directly, preventing flood-back and protecting compressors in systems with significant coil pressure drop. The sweat ODF connections ensure a clean, permanent installation, while the 5-foot capillary tube gives technicians the flexibility needed for proper bulb placement and accurate sensing.
