Danfoss 018F6857 | BF Series Solenoid Coil, 230V AC 50/60Hz, 8W, IP65
Danfoss 018F6857 BF-type solenoid coil. 230V AC 50/60Hz, 8W, IP65 with DIN 43650 A connector, for EV210B/EV220B/EV310B/EV320B valves.
Product Overview
The Danfoss 018F6857 is a BF-type solenoid coil (Type B flange with Ø13.5 mm center hole, 27.5 mm height) designed to mount on Danfoss EV210B, EV220B, EV310B, and EV320B pilot-operated and direct-acting solenoid valves. It operates on 230 V AC (50/60 Hz) at 8 W power consumption and achieves IP65 protection when used with a proper DIN 43650 A (EN 175301-803 Form A) connector. The coil is the standard 230V AC option for the widely used DN15–DN50 EV220B / EV210B series in European HVAC and industrial installations.

Danfoss EV210B, EV220B (PN16/PN25), EV310B, EV320B (with Type B yoke)
Key Features
Direct Fit for Danfoss Solenoid Valves: Exact BF-Type B flange matches the yoke on EV210B/220B/310B/320B bodies — no adapter needed.
DIN 43650 A Standard: Uses the universal Form A connector (e.g., Danfoss 018F6721 or generic DIN A plug with LED/varistor options) — easy to source worldwide.
8W AC — Low Heat: Moderate power draw with good holding force; AC coil self-de-energizes on zero-cross — no DC holding circuit needed.
IP65 When Properly Connected: Achieves dust-tight / water-jet protection with a correctly seated DIN 43650 connector and rubber gasket.
Applications
HVAC & Building Services: Powering 230V AC solenoid valves in chilled/hot water loops, boiler feed lines, and cooling tower bypass.
Industrial Process: Switching process water, compressed air (check valve rating), or light oil with DN15–DN50 Danfoss solenoid valves.
Retrofit / Spare: Replacement coil for existing Danfoss solenoid valve installations originally shipped with 230V AC coil.
Irrigation & Agricultural Pumping: 230V AC coil matches common European single-phase supply for main-line solenoid shut-off valves.
Note: The DIN 43650 A connector (plug + gasket + screw cap) is NOT included with the coil — common match is Danfoss 018F6721 (with LED + varistor protection) or a generic Form A plug. For 24V DC / 24V AC / 110V AC coils on the same valve bodies, see other BF coil codes (e.g., 018F6701 = 24V DC 6W, 018F6758 = 230V AC 8W older code — verify current catalog). Always confirm your valve's yoke type is "Type B" before ordering — older Type A (low-profile) coils are not interchangeable.
