HBProducts | Modulating Pilot Valve
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.
Product features
- Short positioning time (approx 1 s)
- High resolution
- Hermetically sealed
- Versatile electrical interface with terminal housing ZM..
- Friction free
- Robust and maintenance-free
