Timely, effective valve seat repair means higher efficiency and more uptime. Failing valves often require attention at the most inconvenient of times. Maintenance also extends the life of valves, reducing overall lifetime costs.

Valve grinding in practice

The objective of grinding valve seats is to achieve a dense, flat surface with crosshatch pattern. This is achieved by creating friction, evenly and in the right measure, between the surface and the abrasive material. Valve grinding can be carried out in-situ or in the workshop.

LarsLap manufactures a range of valve grinding and valve lapping machines, covering valves from 10 to 1300 mm diameter with overlapping machine sizes.  LarsLap valve grinding machines with individually driven grinding heads combine rapid results with unsurpassed valve seat flatness.

Accessories that make your LarsLap machine even more versatile.

The abrasive material is the part of the equipment that is in contact with the valve seat and performs the actual grinding. High quality results can only be achieved with quality abrasives.

The choice of abrasive material depends on the material of the valve seat and its condition. Check our guide for recommendations.

Read what is happening at LarsLap at the moment.

LarsLap pioneered the technology with individually driven grinding heads some 30 years ago. The need for achieving excellent results in a short space of time was initially identified in the nuclear industry, where the time technicians can work on a valve is limited. Today, LarsLap is helping to improve productivity in a wide range of industry sectors.
