Description
The Trane VAL07241 4-Ton Expansion Valve 0.31″ ODF x Chatleff is a refrigerant metering system used to control the flow of R-410A into the evaporator coil based on cooling demand. It regulates entry by sensing coil conditions and adjusting flow to maintain proper superheat, preventing liquid refrigerant from returning to the compressor. This is typically installed at the evaporator inlet connection, where it interfaces with both brazed and Chatleff fittings. In air conditioning systems, it supports controlled distribution, improving heat exchange stability and maintaining consistent cooling performance under changing load conditions.
