Application
Ideal for use in split-system air conditioners and heat pumps using R410A refrigerant. The external equalizer port ensures accurate superheat control in evaporators with significant pressure drop, while the internal check valve supports heat pump reversing cycle operation. The 195 PSI MOP charge protects the compressor from liquid slugging during high-load conditions. The 30″ capillary tube provides installation flexibility in a variety of equipment configurations.
