Valve Grinding Gate, Check, Safety, Control Valves & Gate Valve Wedges
Model G for valves 6"-32" (150-812mm)*
Drive heads on the model G incorporate individually driven discs, permitting rapid and efficient grinding of exceptionally smooth, flat surfaces for tightest possible seats.
The Model G drive head carries five telescopically adjustable radial arms to which the grinding heads are attached. Grinding heads are available in a range of lengths and sizes, permitting numerous combinations within the 150–1300 mm range (6”–32”).
Other accessories are available to increase the capacity to 52" (1320mm)
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).
