Grinding of valve spindles on medium and high speed engines.
The PVG from Chris-Marine is a valve spindle grinding machine developed for on-site grinding of all types of cylinder air-intake/exhaust valve spindles. The machine is portable and can be mounted both horizontally and vertically and is therefore a good solution for grinding onboard vessels.
