By sensing the actual pressure at the evaporator outlet, the valve instantly compensates for internal pressure drops within the coil, preventing delayed valve openings, thermal oscillations (hunting), and dangerous liquid slugging back toward 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
