Danfoss ICS3 25-5 pilot-operated servo valve, 25 mm (1 in) butt weld (ASME B 36.10M Schedule 80), steel, Kv 1.7 m³/h (code 027H2071)

Danfoss ICS3 25-5 pilot-operated servo main valve (code 027H2071) for industrial refrigeration. Straightway steel body with butt weld connections both ends, 25 mm (1 in), to ASME B 36.10M Schedule 80; flow coefficient Kv 1.7 m³/h (Cv 2 gal/min). The ICS 3 main valve carries up to three pilot function modules on its top cover, allowing combined control functions (e.g. constant pressure plus solenoid on/off plus a limiter; pilots 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. Specifications per Danfoss store code 027H2071.

Compatibility

Danfoss ICS 3 three-pilot servo main valve for industrial refrigeration. Function is set by the pilot module(s) fitted to the top cover. Select by Kv/cone (ICS3 25-5) and connection (Butt weld ASME B 36.10M Schedule 80); 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.
