Modulating Refrigerant Valves MVS661N

MVS661 N is a modulating valve for the connection to the refrigerant level control sensor type HBLC. It has a fast reaction time and can be used for ammonia (R717) and all standard refrigerants, noncorrosive gases/liquids and CO2 (R744). It is not suited for use with inflammable refrigerants.
These valves are powered by a proportional electric device, that close in case of power failure.
