Unlike models with internal equalization, the <b data-path-to-node=\"5\" data-index-in-node=\"307\">Refrigerant Boys TEZ2 series<\/b> features a 1\/4\u2033 SAE Flare port for external equalization, which is essential when the system uses liquid distributors, multi-circuit coils, or components that cause significant pressure drops. By detecting the actual pressure at the evaporator outlet on the suction line, the valve ensures an immediate response to changes in thermal load, eliminating hunting and preventing dangerous liquid return to the compressor.<\/p>\n<p data-path-to-node=\"6\"><b data-path-to-node=\"6\" data-index-in-node=\"0\">Strengths &amp; Advantages:<\/b><\/p>\n<ul data-path-to-node=\"7\">\n<li>\n<p
