Application
This TXV is ideal for use in residential and light commercial split systems, package units, and refrigeration equipment operating on R-22 or R-407C refrigerant. The external equalizer port connection is essential for evaporators with a significant pressure drop across the coil, ensuring the valve responds accurately to true evaporator outlet conditions rather than inlet pressure alone. The 5-foot capillary tube provides installation flexibility, allowing the sensing bulb to be properly positioned on the suction line for optimal superheat control.
