Lapping solutions for valve manufacturers
12 July 2018
Superabrasives specialist, Engis UK offers valve manufacturers a range of lapping solutions, from complete machine systems to lapping plates, accessories and consumables, addressing key production requirements and ensuring the job is done 'right first time'.

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 - leading to costly onsite repairs.
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 required to extend the life of these valves.
For lapping ball valves, Engis has a range of diamond compounds, powders, slurries and lubricants, while Engis L compound is said to provide superior cut rates and finishes for a wide range of valve seating applications. Engis diamond slurries, compounds and lubricants are suitable for precision polishing of the balls themselves.
