Danfoss ICF 20-4-13 Flexline valve station (code 027L3093). The ICF valve station combines several refrigeration control functions in one steel housing — for this configuration: Stop valve (ICFS 20), Filter (ICFF 20), Electronic expansion valve (ICFA 20), Stop/check valve (ICFN 20). Connection size 20 mm, connection standard EN 10220 (butt weld). 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).
