The KE2 Therm RSV electric expansion valve is a stepper motor actuated valve, designed for
refrigeration applications. The RSV uses a unipolar stepper motor that provides high precision
control. Upgrading a system with an RSV will increase system efficiency and provide the best, most consistent superheat control, and eliminate the headache of adjusting superheat.
