Stepper Motor Valve

Technical data: Carel E2V

Carel E2V stepper motor valve for the connection to the refrigerant level control sensor type HBLC, HBX and HBX-OVC. It can be used for all refrigerants and has a fast reaction time.

We offer Carel stepper motor valves as Ø10 (Carel “E2V** CS 000) for CO2 & HFC and Ø13 (Carel E2V** BS 100) for NH3.

The stepper motor valve requires only supply and connection from the “HB-xx/S” sensor and requires no additional stepper motor driver.
