Failure Symptoms

Initial symptoms of a failing valve may include a slight delay or stiffness when operating control levers. Over time, this can progress to jerky or unpredictable hydraulic movements and potentially a complete loss of function for the affected hydraulic circuits, impacting operational efficiency.

Installation Tip

Before removing the old valve, carefully label all hydraulic lines and electrical connections to ensure correct reassembly. Avoid overtightening the valve body or fittings, as this can lead to cracks or leaks.

Service Note

Inspect the associated hydraulic lines for any signs of wear or damage, and check the hydraulic fluid level and condition.
