For over thirty years, we have been specialized in the production of vacuum seal rotating valves and we have developped many solutions aimed to the optimization of their performances.

The vacuum seal rotating valves manufactured by Storci incorporate an innovative lateral packing seal system which we have designed to improve “flour-tightness”, preventing flour from coming into contact with the lubricating grease (anti-seizure function). In this way optimum component operation and a longer service life are guaranteed. All Storci vacuum seal rotating valves are available in versions with a three.

Components restoration to "as new" condition

We recondition used vacuum seal rotating valves in our workshop including:

boring of the cast iron stator;
impeller grinding and scraper blade replacement;
replacement of bearings and sealing rings;
repainting in the original colour;
correct operation testing.

We guarantee an assistance and reconditioning service for Braibanti vacuum seal rotating valves, thanks to our in-depth knowledge of these components acquired in over 30 years of study
