Kobelco YN30V00105R120 YN30V00105R150 Pilot Operated Valve for SK200-8 Excavator

Product Details

Product Overview

This genuine Pilot Operated Valve, carrying the OEM part numbers YN30V00105R120 and YN30V00105R150, is a critical hydraulic control component specifically designed for the Kobelco SK200-8 excavator series. As a direct OEM replacement, this valve ensures precise hydraulic pilot pressure control, enabling smooth and responsive operation of the excavator’s main control valve and attachment functions.

Sourced from Japan and verified as a genuine component, this pilot valve is essential for maintaining the original performance standards of your Kobelco machinery. It is commonly used in the SK200-8 model to regulate the flow and pressure of hydraulic fluid to the main spools, directly impacting digging force, swing speed, and overall machine controllability. Replacing a worn or failing pilot valve restores fine control and prevents erratic machine movements.

FAQ

Q: How do I confirm this valve fits my SK200-8 machine?
A: Please physically check the part number stamped on your current pilot valve. It should match either YN30V00105R120 or YN30V00105R150. This valve is specific to the SK200-8 model and is not interchangeable with other series like the SK200-6 or SK200-10 without modification.

Q: What are the symptoms of a failing pilot operated valve?
A: Common symptoms include jerky or sluggish machine movements, difficulty in performing fine grading operations, hydraulic oil overheating, or the machine creeping when the joysticks are in neutral. If you experience these issues, inspecting and replacing the pilot valve is a critical diagnostic step.

Q: Can I install this valve myself, or do I need a technician?
A: While the physical removal and replacement of the valve is straightforward (involving disconnecting hydraulic lines and unbolting the valve), the system must be purged of air and the pilot pressure may need to be adjusted to spec after installation. We recommend installation by a qualified hydraulic technician to ensure proper bleeding and adjustment, preventing damage to the main control valve.
