• A portable, easy to mount, cutting, milling and grinding machine.
• Ideal for globe, safety and control valves.
• As a rule, control and reduction valves of the globe type have an integrated plug that narrowly constrains the tolerances for the seat position. In the event of damage to the seat, it is often unfeasible or extremely expensive to dismantle the valve from the pipe system in order to repair it in the workshop. If the damage is to be repaired in situ, the device to be used must be of stable construction without being bulky or heavy. As these valves show a large range of dimensional variation, the repair device must be adaptable to the largest possible mounting and seat area.
• Possible repairs include the grinding of gasket surfaces damaged by crushing or abrasion, of damage cylindrical a plane control areas, various treatments of gasket welds and cutting the seats in situ.
• The LarsLap model C has been designed to ensure flexibility as well as speed and ease of handling.

LarsLap Lapblock makes grinding valves and gasket rings eas­ier and more affordable. A unique diamond composite material provides a more reliable result and superior durability. Since neither grinding paste nor chemicals are needed, Lapblock also helps you reduce the environmental impact of your work.

Easier grinding
The grinding disc of the LarsLap Lapblock is made from a sta­ble aluminium core coated with a diamond composite surface. This keeps weight low while providing an abrasive surface that lasts significantly longer than conventional discs.

When grinding, all you need to add is ordinary water. No grinding paste is needed, which eliminates the risk of old abrasive particles being left on the disc and interfering with grinding. The grinding disc of the LarsLap Lapblock is available in different grades of coarseness, from 1 urn to 40 nm. You can easily change the disc yourself.

After grinding, the unit can be cleaned quickly and easily. The grinding disc is easily reconditioned using the cleaning block provided and rinsed with water. The lattice pattern of the disc is specially designed to provide optimum grinding and water drainage.

Lower costs
LarsLap helps you cut costs in several ways. Thanks to the unique diamond composite material, the grinding disc lasts significantly longer than normal discs. The disc can also be smoothed off when necessary, so you don't have to buy a new disc when you decide it is worn out. Instead, you simply send it in for maintenance and receive it back in as-new condition.

Because the abrasive material already contains diamond, there is no need for you to purchase or keep a stock of expen­sive diamond fragments in various grades of coarseness.

Practical carry case
LarsLap Lapblock is supplied complete with a practical carry case made from tough plastic, containing a water bottle, clean­ing block and stainless steel container to collect the water that runs off during grinding. When cleaning the unit, you can easily remove this container from the case to empty it and rinse it out with water.

LarsLap Lapblock is suitable for stationary use in the work­shop and can readily be taken along for on-site work.

A greener alternative
Using LarsLap Lapblock not only simplifies grinding work and cuts costs. You are also helping the environment, since no chemicals are needed for grinding or cleaning. The absence of chemicals also means you eliminate the risk of skin irritation as a result of grinding work.
