Danfoss 018F6857 BG024DS Solenoid Coil for 24 VDC Valve Control

The Danfoss 018F6857 is a BG024DS high-performance solenoid coil designed for 24 VDC operation. Danfoss lists a nominal power consumption of 20 W, a permitted voltage variation of plus or minus 10 percent, and an ambient temperature range from -40 to 50 degrees Celsius for this catalog number. The coil converts electrical energy into the magnetic force required to operate a compatible solenoid valve, supporting dependable on-off control in industrial fluid systems.

This coil is relevant to refrigeration, cooling, water, air, oil, steam, and process-control applications when paired with an approved Danfoss valve and suitable media conditions. Danfoss commonly supplies valve bodies and electrical coils separately, allowing engineers to match voltage, frequency, connection, enclosure, and environmental requirements to the installation. Catalog number verification is critical because visually similar blue coils can have different electrical ratings.

Technical Selection Points

• Catalog number 018F6857 and Danfoss type designation BG024DS.
• 24 VDC supply for compatible direct-current control circuits.
• 20 W nominal power consumption under the manufacturer's listed conditions.
• Voltage tolerance of ±10 percent.
• Listed ambient range from -40 to 50°C.
• High-performance coil format for use with compatible Danfoss solenoid valves.

Installation and Maintenance

Before installation, isolate electrical power and relieve pressure according to the machine or plant procedure. Confirm that the coil voltage matches the control supply and that the valve armature, tube, and coil fastening arrangement are compatible. Incorrect voltage, excessive ambient temperature, damaged insulation, moisture ingress, mechanical obstruction, or energizing a coil without the correct armature assembly can cause overheating or premature failure.

Maintenance teams should inspect connectors, cables, seals, coil retention, corrosion, and signs of heat damage. If a valve fails to actuate, distinguish between an electrical coil fault, control-signal problem, incorrect voltage, blocked valve, pressure differential issue, and mechanical wear. A coil replacement will not correct contamination or damage inside the valve body.

Procurement Checklist

Use the full code 018F6857 when requesting a quote. Confirm 24 VDC supply, connector or terminal arrangement, enclosure needs, valve model, orifice, medium, pressure, duty cycle, ambient temperature, approvals, and quantity. The supplied photograph shows a blue Danfoss coil consistent with the requested product type, but the label is not sharp enough to verify every electrical field. Final acceptance should rely on the printed catalog number and electrical rating.

For control-panel design, allow for the coil's steady electrical load, switching device rating, overcurrent protection, cable size, and any suppression required by the control manufacturer. Check voltage at the coil while energized, especially on long cable runs. Low voltage can prevent complete valve movement, while excessive voltage or temperature can shorten insulation life.

Store unused coils in clean, dry packaging and protect the connector area from contamination. During receiving inspection, compare the code number, voltage, current type, connection style, color, and approvals with the purchase order. Do not select a replacement only by physical appearance, because Danfoss manufactures similar housings for several voltages and frequencies.

For stock, price, lead time, and compatibility support for Danfoss 018F6857, provide the existing valve and coil nameplates together with the application conditions. We can assist with industrial replacement sourcing and specification review.
