Product series: 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.

We recommend using the "Siemens Modulating Valve Selection Program" for calculating valve size [kW], which can be downloaded for free under the "Downloads" tab.

We recommend Siemens valves for evaporators larger than 150 kw when using ammonia.

Product series: M2FP03GX

M2FP03GX is a modulating valve for the connection to the refrigerant level control sensor type HBLC. It can be used for all refrigerants and has a fast reaction time. The modulating valve requires only supply and connection from the HBLC.

• 2-port modulating pilot valve with magnetic actuator, PN32, AC 24 V, DC 0...10 V / 4...20 mA / 0...20 Phs to control main valves
• Hermetically sealed 2-port valve as a control valve for main valves from 2” to 5”.
• PN32 with threaded connections
• For use with refrigerants such as R22, R134a, R404A, R407C, R507 and ammonia R717

The Siemens M2FP Series is for capacity requirements of 6 – 354 Kvs [m3 /h]. We recommend Siemens valves for evaporators larger than 150 kw.
