Lapping solutions for valve manufacturers

Ensuring a good seal is critical to valve manufacture, whether it is a gate, ball or butterfly valve, and the extreme environments in which valves operate can sometimes cause leaks to develop in a system.

For high pressure valves, or those exposed to corrosive gases or fluids, a gasket or O-Ring cannot be used as the sealing approach. In these cases, where two high precision metal surfaces need to be mated and different surface textures are required to avoid galling, Engis Hyprez Flat Lapping Systems can offer the fit and finish that is required to extend the life of these valves.

For lapping ball valves, Engis has a complete range of diamond compounds, powders, slurries and lubricants.
