Abstract: A valve assembly including at least one valve control group, which has two valve units. Each valve unit contains a valve tappet, which is arranged in a valve chamber and which passes through an overflow opening framed by a valve seat and has a shut-off segment facing the valve seat. In addition, each valve tappet has a first closure segment and a second closure segment, which each close one of two valve chamber segments in a sealed manner. The diameters of the two closure segments of each valve tappet are equal among each other and also equal to or slightly less than the diameter of the overflow opening.

Abstract: A valve assembly includes a valve unit, which is mounted on a valve support and composed of a valve and a connecting bridge fitted to the valve. The connecting bridge is used for electrically contacting the valve to signal transmission means located in the valve support. It has an L-shape with a first L-leg overlapping the valve and a second L-leg projecting downwards laterally adjacent to the valve. For its location on the valve support, the valve is provided on its underside with a mounting base with a laterally protruding base projection, with which the connecting bridge engages with its second L-leg for stabilisation.

Abstract: A sorting device which is suitable for sorting parts by means of air blasts and which includes at least one sorting unit which includes a valve support fitted with sorting valves. Each sorting valve is capable of optionally connecting a sorting passage ending in a sorting nozzle to a feed passage and of disconnecting it therefrom. In addition, several or all of the sorting passages of the sorting unit are—independently of the sorting valves—connected to a common purge air passage, so that purge air can flow through them without any involvement of the sorting valves, with the result that no impurities enter the sorting passages.

Abstract: A compressed-air system having a safety function and a method for operating such a compressed-air system. The compressed-air system contains two working valves, which each can selectively assume an aerating position that aerates a load and a venting position that vents the load. Both working valves are redundantly connected on the output side to the load by means of a separating device. The separating device allows one or the other of the working valves to be separated, while the aeration of the load is maintained, in order to subject the one or the other working valve to an examination of the switching function of the one or the other working valve.

Abstract: A diaphragm valve has a valve housing and a valve member movable relative to said housing. The valve member includes a diaphragm carrier that can be driven to execute a switchover motion having a sealing diaphragm mounted thereon, which delimits a valve chamber in which a valve seat is found. The sealing diaphragm has a sealing section opposite said valve seat belonging at least partially to a loose diaphragm section of the sealing diaphragm, which can lift from the diaphragm carrier to reduce the stress on the sealing diaphragm when said diaphragm carrier is removed from the valve seat during switching.
