Description
The US Motors 5642 is a precision-engineered Thermal Expansion Valve (TXV) designed for reliable refrigerant metering in low-temperature refrigeration applications. Carrying model designation HFE 1 1/2 RZ 5FT 3/8 x 1/2 SAE ANG, this valve delivers consistent superheat control and efficient system performance in demanding commercial and industrial refrigeration environments.
Key Features
- Refrigerant: Rated for R502 systems
- Capacity: 1.5 Ton — optimized for low-temperature charge applications
- Body Style: Angle body configuration for flexible installation in tight spaces
- Connections: 3/8″ inlet x 1/2″ outlet, SAE flare fittings for leak-free connections
- Capillary Tube: 5-foot capillary tube for accurate bulb placement and sensing flexibility
- Equalization: Externally equalized design compensates for distributor and evaporator pressure drop, ensuring accurate superheat control across the entire evaporator
Application
This externally equalized TXV is ideal for low-temperature refrigeration systems where evaporator pressure drop is a concern. The external equalizer port connects downstream of the evaporator outlet, allowing the valve to accurately sense and respond to true evaporator outlet pressure — maximizing evaporator efficiency and protecting the compressor from liquid slugging.
