Danfoss ICF 20-4-90 Flexline valve station, 20 mm, ASME B 16.11 (code 027L4578)

Danfoss ICF 20-4-90 Flexline valve station (code 027L4578). The ICF valve station combines several refrigeration control functions in one steel housing — for this configuration: Manual regulating valve (ICFR 20B), Filter (ICFF 20E), Solenoid valve (ICFE 20H), Stop/check valve (ICFN 20). Connection size 20 mm, connection standard ASME B 16.11 (socket 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).

Compatibility

ICF Flexline modular valve station for industrial refrigeration. This code is the factory build ICF 20-4-90 (Manual regulating valve (ICFR 20B), Filter (ICFF 20E), Solenoid valve (ICFE 20H), Stop/check valve (ICFN 20)). The station bolts into a 20 mm line (ASME B 16.11, socket weld); individual function modules can be serviced without removing the housing from the line. Confirm line size, connection standard, refrigerant and required functions match this configuration before ordering.
