Siemens MVS 6.3N-IP HB Products Modulating Refrigerant Valve, 24V DC

The MVS661..N refrigerant valve is designed for modulating control of refrigerant circuits including chillers and heat pumps. It is suitable for use in expansion, hot-gas and suction throttle applications. In addition to ammonia (R717), the valve can handle all standard safety refrigerants, noncorrosive gases / liquids and CO2 (R744). It is not suited for use with inflammable refrigerants.

MVS661 can be controlled and supplied directly by a HBX vapor quality sensor or a HBSLC/HBSLT Level sensor. This reduce cabling cost, PLC programming cost and PLC hardware cost.
