The asasuction unit is screwed to the asaadapter flange, which is welded to the tank. Due to low installation costs and compact design, purchasing asa suction units is cost effective. A switch (mechanical or inductive) can be mounted on the standard block for monitoring matters. The adapter flange may only be welded with demounted butterfly flange.
Request more information on this new type of adapter that combines the welding flange for the butterfly valve with a thread port to the suction strainer.
Our new lockable pin is an optional pin to protect unforeseen or not qualified operation of the hand lever of the butterfly valve. This locking pin is available on request on each size of our butterfly valves.
