RETHINKING REBUILDS?

Most rebuilds from other companies simply involve tipping the rotors and filling worn areas — a temporary fix that can actually shorten valve lifespan over time!

Rotary Airlock takes a different approach: WE REENGINEER. We restore valves ANY MAKE, ANY MODEL to like-new condition — EVEN BETTER THAN NEW — through precision rebuilding solutions designed to extend the overall life expectancy and performance of your system at a fraction of the price of a new one.

WE HAVE A 3-STEP PROCESS . . .

One:

Machine the housing back to concentric and parallel specifications.

Two:

Manufacture new endcaps and a rotor to custom-fit the restored, like-new housing.

Three:

Replace all bearings and seals.

The end result is a like-new — or even better-than-new — valve at rebuild pricing!
