RSK/P-Flap Valve

RSK/P-Flap Valve 1


Floater-supported RSK/P-Flap Valves reliably protect against backwater and flooding. Using adjustable weighted lever mechanics in combination with a floater, opening and closing times can be precisely set. The flap gates are available in nominal widths DN 250 to DN 2500 in both rectangular and circular formats.

RSK / P flaps consist of a swiveling flap body arranged underwater. They are stored above the discharge opening and are open in the basic position.

A combined weight and float mechanism and a moment cam provide automatic closing and opening at defined water levels.

RSK / P flaps do not generate hydraulic losses as they close only when needed to prevent backflow.
