Channel flap
made of stainless steel

The three-sided sealing channel flap closes off channels and flumes. The flap is mounted on a centrally rotating bearing and can therefore be operated with little effort. Its extremely compact, space-saving design makes it particularly suitable for use in overbuilt or covered channels. Due to their overall height, conventional sluice gates cannot be used there.
