KE2 RSV Electric Expansion Valves

High precision, stepper motor actuated Electric Expansion Valve (EEV), designed for refrigeration applications.
  • Overview
  • Specifications
The KE2 RSV is designed for refrigeration applications and delivers reliable, precise stepper motor actuated superheat control when paired with KE2 Therm’s proprietary superheat control algorithm.  A new or existing system outfitted with a properly sized KE2 RSV & KE2 Therm controller will increase system efficiency, provide consistent superheat control across varying ambient & system conditions, pull down more quickly, and eliminate the headache of adjusting superheat manually. With KE2 SmartAccess, the superheat setting can be changed remotely, and all related variables viewed in real-time.
