Model 43-46 Automatic Control Valve

Oct. 26, 2020

The Cla-Val Model 43-46 is an automatic control valve typically installed on the discharge side of a filter vessel. Its purpose is to limit the maximum flow rate through the filter vessel, preventing the filter vessel from exceeding its maximum flow rate while providing water defense shutdown capabilities. It offers redundant shutdown capability in water defense applications with the ability to shutdown hydraulically by a signal from a Cla-Val Float Control installed in the sump of the filter vessel or electronically when water is detected. This would be via electronic water detection technology offered by others. It also maintains a minimum differential across the valve to ensure positive shutdown if a water slug event takes place.
