摘要： A pneumatic hand valve comprising a valve housing (1) with two and preferably four first seat valves (1g, 19) which are connected to pressure recipients and arranged in a common plane around, and oriented with their valve cones radially towards, a centre line (A-A) perpendicular to said plane, on which centre line there is disposed a control means (15) common to the seat valves, a base plate connected to the housing, such that the plate and the housing are axially movable relatively to each other along said centre line between an outer and an inner limit position, the base plate including a second seat valve (3g, 9) connected to a compressed-air supply (13) and oriented with its valve cone (9) along the centre line, the valve housing and the base plate including interacting means (1b, 3d, etc.) which are arranged in such a way that when one of the first seat valves is open, the recipient connected to said valve will be in communication with the ambient atmospheric pressure, and the second seat valve will be closed when the valve housing and the base plate are in or proximate to one of the limit positions, whereas said recipient will be in communication with the compressed-air supply and communication with the atmospheric pressure will be interrupted when the valve housing and the base plate are in or proximate to the other limit position.
