Vickers Solenoid Coil 617471 | 24VDC 39W K20-17 | 6041017-001

LIC Hydraulic offers the Vickers K20-17 Series solenoid coil, a robust electrical actuator designed for the most demanding industrial hydraulic applications. Available under part numbers 617471 and 6041017-001, this 24VDC coil is the direct replacement for actuators used on Vickers DG4V-3 directional control valves. Rated at 38W/39W, it provides the high-force magnetic field necessary for rapid and reliable valve spool shifting. With an IP65 rating and Class H insulation, this coil is engineered to operate efficiently even in high-temperature environments or areas exposed to fluid splashing.

Key Technical Advantages

• Thermal Durability: Constructed with premium copper winding and high-grade insulation, this coil resists thermal fatigue during long-duration duty cycles, preventing internal short circuits.

• Chemical & Oil Resistance: The encapsulation material is chemically inert to most hydraulic fluids and cutting oils, ensuring the external housing won’t crack or degrade over time.

• Precision Magnetic Force: Calibrated specifically for Vickers valve geometries, ensuring consistent shifting times and preventing solenoid hum or vibration.

• OEM Reliability: Our 617471 coils meet or exceed original equipment specifications, offering a cost-effective solution with guaranteed fitment and performance.

Application Areas

• Industrial Automation: Power units for assembly lines, metal forming presses, and material handling systems.

• Machine Tools: Control circuits for lathes, milling machines, and grinders.

• Injection Molding: Auxiliary functions for plastic and rubber processing machinery.

Expert Maintenance Tips

• Never Energize in Free Air: Always install the coil onto the valve armature before applying power. Energizing a “naked” coil causes excessive current draw and will lead to an immediate burnout.

• Check Electrical Connector: Ensure the DIN connector screw is tightened properly to maintain the $IP65$ seal. A loose plug allows moisture ingress, the primary cause of contact corrosion.

• Heat Management: Ensure the ambient temperature around the solenoid does not exceed rated limits. If multiple valves are stacked, ensure adequate air circulation to prevent heat accumulation.
