This solenoid valve coil is a key electrical component for controlling hydraulic valve actuation in Volvo excavators, providing the magnetic force to shift valve spools. It is designed for precise voltage and current requirements, ensuring reliable operation, unlike a burnt or shorted coil which will fail to energize the valve. Operators may experience a loss of hydraulic function in the controlled circuit, or the valve may remain stuck in one position when this coil fails.

Flush hydraulic lines before fitting new components. Use only manufacturer-specified hydraulic fluid. Check O-rings and backup rings for correct orientation. Bleed air from system after installation.
Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.
The primary symptom of a failed solenoid coil is the immediate loss of hydraulic function controlled by that specific valve. If the valve remains stuck in a position, it can lead to unintended machine movement or an inability to perform a required operation. Ignoring a faulty solenoid coil can result in operational downtime and potential safety hazards due to unpredictable machine behavior.
Ensure the electrical connector is clean and free of corrosion before attaching the new coil. Avoid forcing the coil onto the valve body; it should slide into place smoothly.
Inspect the hydraulic valve spool and seals for wear or damage when replacing the solenoid valve coil.
