PRO KLAPPE® butterfly valve with restraint loose flanges

The PRO KLAPPE® butterfly valve is provided with a proportional action sealing system. The sealing is accommodated in the body of the butterfly valve. When open, the same pressure is admitted to the butterfly valve from all sides, thus reliably preventing unintended deformations of the gasket. As soon as the PRO butterfly valve is moved to closed position, the valve seal is pressed against the valve disc. The contact pressure depends on the water pressure.

The proportional action sealing system ensures reliable sealing, on the one hand, and a long service life due to low wear of the sealing, on the other hand.

The PRO KLAPPE® butterfly valve is provided with the same loose flange system as the exchange gate valve. Therefore, apart from being used in new constructions, the butterfly valve is mainly suitable for exchanging existing valves. The flat gaskets are already included in the barrel gaskets. Therefore, no keying is required between the flanges.
Moreover, the loose flange system has some advantages in terms of storage.
Apart from its real function as shut-off valve, the PRO KLAPPE® butterfly valve can also be used as dismantling piece because of the integral loose flange system (no additional dismantling piece required).
