Description
The US Motors 6078 is a precision-engineered Thermostatic Expansion Valve (TXV) designed for reliable refrigerant metering in 1-ton R22 refrigeration and air conditioning systems. Featuring an externally equalized design and a medium-temperature charge, this valve delivers accurate superheat control across a wide range of operating conditions, making it an ideal choice for both service replacement and new installations.
Key Features
- 1-ton (1 HC) capacity, matched for R22 refrigerant systems
- Medium-temperature charge for optimized performance in standard refrigeration and comfort cooling applications
- SAE external connection with a 5-foot (5 FT) capillary tube for flexible sensing bulb placement
- Externally equalized design compensates for pressure drop across the evaporator, ensuring accurate superheat control
- VLF (Valve Less Flange) configuration for streamlined installation
- Durable construction built to withstand demanding HVAC/R operating environments

Why Choose the US Motors 6078 TXV?
The externally equalized design of the US Motors 6078 makes it especially well-suited for evaporators with significant internal pressure drops, such as those using refrigerant distributors or multi-pass coil arrangements. The 5-foot capillary tube provides ample reach for proper sensing bulb placement, helping technicians achieve accurate superheat settings without compromising system efficiency. The VLF (less flange) design simplifies installation in tight spaces where flanged connections are impractical.
