Danfoss ICF 25-4-42S3-25 Flexline valve station, 40 mm, ASME B 16.11 (code 027L4237)

Danfoss ICF 25-4-42S3-25 Flexline valve station (code 027L4237). The ICF valve station combines several refrigeration control functions in one steel housing — for this configuration: Stop valve (ICFS 25), Filter (ICFF 25E), Control valve (ICFG 25-25), Stop valve (ICFS 25). Connection size 40 mm, connection standard ASME B 16.11. Maximum working pressure 65 bar (943 psig); media temperature range -60 to +120 C. The ICF Flexline modular concept replaces a string of individually-mounted valves with a single station, reducing weld joints and leak paths. For low- and high-pressure refrigerants in pumped liquid, liquid injection, liquid drain and hot-gas lines, including R717 (ammonia) and R744 (CO2).

Compatibility

ICF Flexline modular valve station for industrial refrigeration. This code is the factory build ICF 25-4-42S3-25 (Stop valve (ICFS 25), Filter (ICFF 25E), Control valve (ICFG 25-25), Stop valve (ICFS 25)). The station bolts into a 40 mm line to ASME B 16.11; individual function modules can be serviced without removing the housing from the line. Confirm line size, connection standard, refrigerant and required functions match this module string before ordering.
