Frequently Asked Questions

The ball-valve assembly is listed for the GH 833 series (models 249318 and 249617) in OEM parts documentation. Please verify your machine's model and serial number before ordering.

While aftermarket valves may fit mechanically, using the genuine Graco 120140 ensures correct material, tolerances and compatibility with the system. For high-pressure hydraulic assemblies, OEM reliability is strongly recommended.

After installation, check for any leaks around the valve body, verify proper flow under pressure and listen for any irregularities or noise. If performance is abnormal, inspect the valve seating, correct torque and clean any adjacent contamination.

If your machine model is not listed above, consult the OEM parts manual or contact your authorised distributor to confirm compatibility before ordering.
