Danfoss ICF 20-6-99 carbon steel valve station, 20 mm, EN 10220 (code 027L3701)

Danfoss ICF 20-6-99 Flexline carbon steel valve station (code 027L3701). The ICF Flexline valve station combines several refrigeration control functions in a single carbon steel housing, replacing a string of separately-mounted stop, filter, solenoid, regulating and motor-operated valves with one welded-in station. This is a 6-function-module (ICF 20-6) configuration with 20 mm butt weld end connections to EN 10220. Maximum working pressure 65 bar (943 psig); media temperature range -60 to +120 C. Applicable to HCFC, non-flammable HFC, R717 (ammonia) and R744 (CO2) in pumped-liquid, liquid-injection and hot-gas lines. Supplied as a complete factory-assembled and pressure-tested station.
