Application
This TXV kit is ideal for HVAC technicians and contractors upgrading or servicing First Company air handlers and fan coil units to operate with R454B refrigerant. Proper TXV selection is critical to system performance — using a valve calibrated for R454B ensures correct superheat control, protects the compressor, and maximizes energy efficiency in residential and light commercial applications.
Why R454B?
R454B (also marketed as Opteon™ XL41) is a low-GWP A2L refrigerant designed as a near drop-in replacement for R-410A. It offers a significantly reduced environmental impact while maintaining performance characteristics suitable for residential and light commercial cooling systems. Pairing your system with the correct TXV kit, like the 9EVR454B-2, is essential for reliable, code-compliant operation.
