Failure Symptoms

Erratic or sluggish hydraulic operation is often the first sign of a failing NH220 valve. If ignored, the issue can progress to a significant loss of lifting or digging power. Unaddressed, this can lead to an inability to perform essential work functions, impacting productivity.

Installation Tip

Ensure the hydraulic system is properly depressurized before attempting removal to prevent fluid spray and injury. Avoid overtightening the valve body mounting bolts, as this can distort the housing and cause leaks.

Service Note

Inspect the hydraulic fluid for contamination and check the hydraulic filter condition when replacing the NH220 valve.
