Claim:
A tiltable valve for discharging foam and other media from a pressurized vessel, comprising: a valve disk for connection to said vessel; a valve body having a holder opening, said valve body being placed in an opening in said valve disk and having a sealing surface at a side facing away from said valve disk; a valve element disposed in said holder opening, said valve element having a tubular portion with a sealing flange at one end and at least one inlet opening in a wall; wherein, in a closed position of said valve, said sealing flange bears on said sealing surface and blocks an entry of said medium requiring discharge in said inlet opening and, in a tilted position of said valve element, said sealing flange and said sealing surface are spaced from each other while forming a gap and said medium requiring discharge is allowed to exit through said gap and said inlet opening; and a blocking body disposed in the tubular portion of said valve element which unblocks, or at least partially closes, said inlet opening in response to the pressure in said vessel, said inlet opening being increasingly unblocked when the pressure drops.
