Application

This TXV is intended for use in York split-system air conditioning and heat pump equipment that utilizes R454B refrigerant. R454B (also marketed as Opteon XL41) is a low global warming potential (GWP) A2L refrigerant increasingly specified in modern residential and light commercial HVAC systems as an environmentally responsible alternative to R-410A. Always verify compatibility with your specific York equipment model before installation.

Why Choose an OEM TXV?

Using a genuine York OEM thermostatic expansion valve ensures the metering device is factory-calibrated for the exact operating pressures, temperatures, and refrigerant charge of your system. This results in more stable superheat control, reduced risk of compressor flooding or overheating, and maintained manufacturer warranty compliance.
