This is an electro-hydraulic proportional solenoid valve (EHPR) used in the hydraulic control system of Volvo excavators, allowing for precise and variable control of hydraulic functions. It is engineered for accurate response to electrical signals, ensuring smooth and proportional operation, unlike a standard on/off solenoid which offers less finesse. Operators may experience jerky or imprecise control of attachments, difficulty in fine-tuning movements, or inconsistent hydraulic power delivery when this valve is not functioning correctly.
Always verify with serial number before ordering.

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 first sign of a problem is often a loss of smooth, proportional control over hydraulic functions, leading to jerky or unpredictable movements. If ignored, the machine's ability to perform delicate tasks will be severely compromised, potentially leading to operational errors or damage to the work piece. Continued use with a malfunctioning EHPR valve can lead to increased hydraulic system stress and wear on other components.
Ensure the electrical connector is securely fastened and the wiring is routed to prevent chafing before powering up the system. Avoid applying excessive pressure or shock to the valve body during installation to prevent damage.
Check the hydraulic fluid for cleanliness and verify the integrity of the electrical control signals to the valve before replacement.
