Danfoss ICS1 25-25 pilot-operated servo main valve (code 027H2064) for industrial refrigeration. Straightway steel body with soldering connections both ends, 28 mm (1 1/8 in), to EN 1254-1; flow coefficient Kv 11.5 m³/h (Cv 13 gal/min). The ICS 1 main valve carries a single pilot function module on its top cover, setting one control function (constant pressure, solenoid on/off, differential-pressure or other pilot, ordered separately). Maximum working pressure 65 bar (943 psig); media temperature -60 to +120 °C (-76 to 248 °F). Suitable for R717 (ammonia), R744 (CO₂), HFC and hydrocarbon refrigerants and their oils.

Danfoss ICS 1 single-pilot servo main valve for industrial refrigeration. Function is set by the one pilot module fitted to the top cover — distinct from the ICS 3 three-pilot valves. Select by Kv/cone (25-25) and connection (Soldering EN 1254-1); the butt-weld, socket-weld and solder variants of the same cone are separate codes. Verify Kv, pilot configuration and refrigerant compatibility against your duty before ordering.
