Valve seat surface defects – solved by our industrial valve grinding procedure. It may be useful to make notes on the type of damage in the valve seat, to try to establish the root cause of the problem. Pinch or jam marks are caused by foreign matter in the pipeline. Usually, these marks are no deeper than 0.05 mm.
