Emerson's XEV22 superheat control valve driver responds to temperature controllers to optimize refrigerant flow through pulse or stepper electronic expansion valves. A fast recovery algorirthm corrects superheat problems more rapidly than traditional systems after verifying a superheat alarm condition. The device supports R22, R134A, R404A, R407, R410, and R507 refrigerants. For more information select a document below.
