XEV22 Superheat Control Valve Driver

XEV22 Superheat Control Valve Driver

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.
