Manual Flow Regulation


Manual regulation when stationary or in motion. Diaphragm stroke length is regulated through a manual rotation of an adjustment graduated wheel with locking knob. The percentage flow rate is indicated on a printed analog scale.

Recommended accessories and spare parts


A number of accessories are available on request to allow the installer / maintainer to be independent for the first scheduled maintenance works. Included into the initial kit of recommended accessories and spare parts you can find: 4.5 meters PE hose, AS valve, spare diaphragm, set of head seals and bottom valve with filter.
