Butterfly Valve Gearboxes

We offer a small selection of gearboxes for the Genebre Art2109 & Art2109A butterfly valves, this includes the Art5975, Art5976, Art5977 & Art2576A to suit up to 2″ (DN50) – 12″ (DN300) valves. All of these gearboxes use a “worm gear” mechanism to ensure a smooth opening and closing action, this prevents water hammer and makes the valves easier to operate compared to standard lever handles.
Installation is simple as these boxes attach to the ISO 5211 bracket found on each valve, they’re handwheel operated with a cast iron body, steel internals and NBR seals. Each unit comes with a position indicator and can be adjusted using the built-in travel adjustment screws.
