Capacity requirements: 0,16 - 6,30 Kvs [m3/h]:
Technical data: MVS661
MVS661 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 require only supply and connection from the HBLC. .
Capacity requirements: 6 - 354 Kvs [m3/h]:
Technical data: M2FP
Modulating pilot valve with magnetic actuator as the controlling element for 2…5“
pilot operated servo valves for modulating control of chillers, or for direct control of low kvs values.
Suitable for use with safety refrigerants such as R22‚ R134a‚ R404A‚ R407C‚ R507
and for ammonia R717. Unsuitable for applications with gas/liquid mixtures.
*We recommend Siemens valves for evaporators larger than 150 kw.
