Danfoss 032U7184
Danfoss EV220B (15-50 range) — 2/2-way servo-operated solenoid valve, brass body, NO version
Danfoss 032U7184 (EV220B 40B G 112N NO000) — the G 1-1/2" BSPP brass, NBR, normally-open servo-operated valve body, supplied without a coil. Danfoss has withdrawn this code as NBR is phased out of the EV220B 15-50 range. Not an identical part. Danfoss rates 032U7184 at a 40 mm orifice and Kv 24 m³/h; this valve is 37 mm and Kv 21 m³/h, roughly 88% of the Danfoss flow at the same pressure drop. Both valves are rated to 10 bar, and this one opens from 0.15 bar differential against Danfoss's 0.3 bar. Body length is 142 mm against Danfoss's 130 mm — this valve is the longer of the two, so check the run before ordering. Coil ordered separately: this valve takes a Series 2 coil, not a Danfoss one.
