The integration of a <b data-path-to-node=\"5\" data-index-in-node=\"297\">1\/4\u2033 SAE external pressure equalization<\/b> port allows the valve to detect the actual pressure at the evaporator outlet, eliminating the impact of internal pressure drops within the heat exchanger or liquid distributor. This mechanism prevents unstable oscillations (hunting), optimizes heat exchange in the coil, and protects the compressor from dangerous liquid slugging.<\/p>\n<p data-path-to-node=\"6\"><b
