A foot valve is essentially a combination of a Check Valve and Filter Screen and is installed at the bottom of a suction line in a well, pond, lake, or other storage vessel.
The check valve component is designed to close off as soon as the pump stops, thus maintaining its prime. The coarse filter screen fitted to the valve’s inlet allows the valve to sit up off the bottom of the well so that it has a large, unrestricted area for suction and minimal pressure drop. It also prevents debris from entering the seating area and stopping the check valve from shutting tightly.
The Mondeo check valves are available in either 304SS or 316SS, both with Viton seats. As for the screens, these can be supplied in either full 304SS or with a nylon connection and 304SS screen. The foot valves are available from 1/4″ (DN8) all the way up to 4″ (DN100) and are rated to 16 bar with female BSP connections as standard.
