The MID Difference
At MID, we’ll strip your valve, inspect it and then offer a quote to undertake the work.
Like everyone else, we’ll replace your rotor tips, your bearings, your seals and your chain, if needed, but it doesn’t end there – we’ll also assess the wear in the body, and if its not too severe, we’ll machine it out. This leaves us with an ever so slightly larger bore than we had before. If the end covers are worn, we can also add plates if needed and machine these back, but the important aspect of this, is that by the time we re-install the rotor, it will have been machined to accommodate the new internal dimensions of the valve, restoring your clearances to their ‘as new’ condition.
Now your rotary valve should last just as long as it did, when it was brand new.
Incidentally, if you don’t want us to undertake the repair work for you, we’ll reassemble the valve and ship it back to you.
Other Manufacturers Valves
We don’t just repair our own rotary valves. If you have a worn out unit from another manufacturer then we can, within reason, repair them to “as new” condition or even improve on the original unit by fitting hard faced components.
