The 32mm stainless steel foot valve screen keeps debris away from the suction inlet while allowing water to enter. It is a screen-only component for use with a compatible valve or suction connection.
The cage surrounds the inlet so water can pass through its openings while larger debris is kept out. It is intended for suction-side screening, rather than fine filtration.
The screen does not contain a non-return mechanism. A foot or check valve provides the non-return action needed to retain water in a suction line. Match the screen connection to the valve or fitting being used.
