How do I match a Danfoss valve or sensor?
Match by part number, refrigerant type, connection size/type, pressure range (for transducers), and electrical/communication requirements (for controllers/EEVs).
Do electronic expansion valves require a controller?
In most applications, yes—EEVs are driven by a compatible controller using sensor feedback to regulate superheat and maintain stable performance.
