Usage: installation in bulkhead (oil pan or gas tank)
The flap is installed in bulkheads of collecting tanks. The integrated seal effectively prevents the medium from flowing back. The lower web has a ramp on the inflow side, so that the inflow is facilitated and the backflow of the medium is impeded.
The bulkhead flap can be used for a collecting tank in the tank, but also e.g. in the oil sump.
