V211 Clapet à papillon à tête inclinée est un type de clapet à papillon qui se compose d’un corps cylindrique, d’un papillon à l’intérieur, d’un arbre qui maintient le papillon, d’un contre-levier et d’un poids. C’est un type qui nécessite moins d’espace d’installation. Même s’il est complètement ouvert, le papillon est situé sur le chemin d’écoulement. C’est la raison pour laquelle il ne peut pas être utilisé dans les eaux usées, mais ne peut être utilisé que dans de l’eau propre.

Slanted Seat Tilting Check Valve Product Features
- Tilting check valves are used at outlet side of pumps.
- When flow begins, disc is pushed forward by effect of flow. Flow continues its travel in direction of pumping.
- When pump begins to slow down to stop, disc begins to close. Check valve closes automatically by assistance of back ow and counter weight which is connected to shaft by counter lever.
- Its closure prevents the water in the pipe line to flow reversely.
- Opening angle of disc must not exceed 80 degrees. If it exceeds, in case of a mechanical tightness, flow moves under the disc and required forces for closure cannot occur. Reverse flow begins; pump starts to turn reverse direction. Serious damage may take place.
- Valve should be installed as shaft in horizontal position.
- Hydrostatic test pressure for seat: PN x 1.1 (e.g.: PN 16 = 17.6 bar); for shell: PN x 1.5 (e.g.: PN16 = 24 bar) according to EN 12266-1.
