Carrier EA02XC444 Expansion Valve 318172-701 a drop below 50 PSIG

a drop below 50 PSIG or a 15 PSI differential indicates the element has reached capacity

System Protection: Reliable isolation capabilities allow for the safe removal of internal components without venting the entire charge

preventing dry-fire scenarios that lead to catastrophic heat exchanger failure

Multi-Positional Mounting: Compact RV52 series housing allows for flexible installation in space-constrained manifold configurations

while outdoor setups require a 13A15-5 vent protector to prevent debris and moisture ingress

Carrier EA02XC444 Expansion Valve 318172-701 a drop below 50 PSIGThe Carrier EA02XC444 Expansion Valve is a critical OEM replacement part engineered for precise refrigerant metering in specialized R 22 cooling systems. As a genuine Thermostatic Expansion Valve (TXV), this component leverages a bi metal composition to maintain a constant superheat at the evaporator outlet, effectively protecting the compressor from liquid slugging while maximizing heat transfer efficiency. Designed specifically for compatibility
