Horizontal or vertical grinding

Drive heads can be angled to grind valve seats in any angle from vertical to horizontal. The valve grinder is easily set up for wedge grinding using the existing clamping system. Supplied with a rugged, customized carrying/storage case complete with all necessary accessories. The case is fitted with specially designed compartments molded to the shape of each component, allowing operators to confirm at glance that all items are in place before and after grinding.

All valve grinders are designed for operational compatibility. They can be run from bench-mountings and driven by pneumatic or electric powered motors. Equipment purchased initially for relatively small diameter ranges can be conveniently upgraded to deal with larger ranges at a later date. This unique degree of flexibility means that grinders can be readily adapted to suit a wide variety of customer needs.

Kemet grinding paper is tested, proved and perfectly fitted to suit your machine under the conditions it will be working in (from 40 grit to 3mic).
