Featuring a Chatleff connection style, this kit delivers a reliable, leak-free interface that simplifies installation and ensures a secure fit in compatible York and Johnson Controls equipment.
Why Upgrade to a TXV Kit?
A thermostatic expansion valve precisely meters refrigerant flow into the evaporator coil based on real-time superheat conditions. This active regulation maximizes system efficiency, protects the compressor from liquid slugging, and maintains consistent comfort levels — especially during varying load conditions.
