Real Project Experience
In one of our projects for an Indian hydraulic valve manufacturer, the customer ordered NG6 directional control valves based on their own design drawings.
During production, we found that the diameter of the valve core required by the customer was different from the standard NG6 specification. However, due to a communication error, the standard valve core was shipped together with the valves.
To solve the issue quickly and avoid delays in the customer’s production schedule, we supplied our standard NG6 valve core assembly to match the valve body. After testing, the valves operated normally and the customer successfully completed their equipment installation.
