KE2 Refrigeration Stepper Valve

KE2 Therm RSV electric expansion valves are stepper motor actuated valves, designed for refrigeration applications. The RSV provides excellent control functionality, as well as features particularly appealing for refrigeration. Upgrading your system with an RSV will increase system efficiency and provide the best, most consistent superheat control, and eliminate the headache of adjusting superheat. New Refrigeration Stepper Valve, with capacity range from 1 to 3.7 tons in R-404A. Among the refrigeration friendly features is the availability of longer cable lengths, allowing easy installation without splicing wires. The RSV is designed with a removable stator, which allows for easier brazing, and for 180 degrees of orientation, maximizing the flexibility of installation and wire routing. The RSV also features several fitting combinations targeted for refrigeration applications. While the compact design makes it convenient for use even on the smallest of refrigeration evaporators. The RSV works with common HCFC and HFC refrigerants, and while the valve caters to refrigeration applications, it is a great choice for air conditioning applications as well.
