ABSTRACT OF THE DISCLOSURE The valve arrangement comprises a disc engageable with a valve seat without attachment and a resilient diaphragm engageable with the disc without attachment. The disc completely covers a passage surrounded by the valve seat and flowed through by a fluid. On the side remote from the valve seat, the disc has a central protuberance with cooperates with a central thrust surface of the diaphragm. The disc and the diaphragm are freely movable in a recess adapted to be flowed through by the fluid, the recess being present in a guide member extending around the valve seat. The recess has an inwardly projecting step with which the diaphragm edge part is urged into engagement. This arrangement leads to a flat compact valve with minimum dead space.
