Rottler VR 8 Centerless Valve Refacer
Rottler's Centerless Grinding System rotates the valve stem on it's own centerline. Precision drive rollers rotate the valve stem and a pneumatic low friction steady rest support the
valve stem similar to a precision balancing machine, resulting in extremely accurate valve stem to valve seat run out. The Rottler Centerless System allows a wide range of valve stem diameters to be ground without changing any collets or chucks.
