Danfoss 018F4120 Coil

The Danfoss 018F4120 is a heavy-duty 230V solenoid coil engineered for precise fluid control in industrial and commercial refrigeration. Specifically built with a BJ240CS actuator and a functional junction box connection, this coil is the direct replacement and cross-reference for Danfoss 018F7681. Designed for high-demand environments, it features Class H winding insulation to maintain electrical integrity under extreme thermal stress, supporting ambient temperatures from -40°F to 120°F. This 13.5 mm actuator size coil is fully compatible with the Danfoss EV series, including EV210B, EV220B, and EV250B solenoid valves. Whether you are servicing a high-pressure liquid line or a suction riser, the 018F4120 junction box coil ensures reliable armature actuation and minimal power consumption (17W at 50Hz / 14W at 60Hz), meeting strict UL 429 and NEMA 2 enclosure standards for field safety and performance.

Key Benefits for Contractors

• Direct OEM Compatibility: Seamlessly replaces legacy 018F7681 units, eliminating the need for mounting bracket modifications in the field.
• Superior Thermal Resistance: High-performance Class H insulation prevents internal shorts during continuous duty cycles in high-ambient mechanical rooms.
• Simplified Wiring: The integrated junction box with 8-inch flying leads provides a secure, code-compliant termination for standard conduit fittings.
• Versatile Frequency Support: Dual-rated for 50/60 Hz operation, making it a versatile stock item for various power supply configurations.
• Broad Valve Integration: Optimized for use with a wide range of EV series valves, ensuring consistent pull-in and hold-in force.

Common Questions

What is the difference between the 018F4120 and the 018F7681?
The Danfoss 018F4120 is the modern technical equivalent and direct cross-over for the discontinued 018F7681. It maintains the same electrical specs and physical dimensions for a drop-in replacement.

Can I use this coil on 208V or 240V systems?
Yes, this 230V solenoid coil is designed to operate within the standard voltage tolerances typical of 208/240V AC power supplies commonly found in commercial HVACR applications.

Does this coil include the valve body?
No, this is a replacement solenoid coil only. It is designed to be installed on existing Danfoss valve armatures with a 13.5 mm diameter.
