Application
This TXV is well-suited for commercial air conditioning and refrigeration systems where precise refrigerant flow control is critical to system efficiency and equipment longevity. The external equalizer port connects to the evaporator outlet, compensating for pressure drop across the evaporator coil and ensuring consistent superheat regardless of load variations. The sweat (ODF) connections make it compatible with standard copper tubing used throughout the industry.
