Siemens ASR2.5N HB Products Valve Insert/Cartridge for MVS661

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.
