The invention relates to a sanitary change-over valve (1) having a valve housing (2) which has one valve inlet (3) and two selectively actuatable valve outlets (4, 5), having a valve piston (6) which is movable from a first switch-over position in which the fluid is guided by way of a flow path that is routed through a first valve outlet (4) to a second switch-over position in which the fluid is guided by way of a flow path that is routed by way of a second valve outlet (5) as soon as that portion of the second flow path that is routed beyond the change-over valve (1) has been released, wherein the valve piston (6) is configured as a hollow body through which the fluid in the course of at least one of the flow paths is routed by way of at least one piston inlet (9) that is disposed on the piston circumference. The change-over valve according to the invention is characterized in that the fluid that is routed by way of the at least one piston inlet (9) in the course of the second flow path is routed by way of a first piston outlet that is provided on that piston end side that faces away from the piston base (10), and in that a flow throttle (12), a flow regulator (11), or a return flow preventer is provided in the first piston outlet (cf. FIG. 1).
A sanitary change-over valve (1) comprising a valve housing (2) which has one valve inlet (3) and first and second selectively actuatable valve outlets (4, 5), a valve piston (6) which is movable from a first switch-over position in which fluid is adapted to be guided by a first flow path routed through the first valve outlet (4) to a second switch-over position in which the fluid is adapted to be guided by a second flow path routed to the second valve outlet (5) as soon as that portion of the second flow path that is routed beyond the change-over valve (1) has been released, the valve piston (6) is configured as a hollow body through which the fluid in the course of at least one of the flow paths is adapted to be routed by at least one piston inlet (9) that is disposed on a piston circumference, the fluid that is adapted to be routed by the at least one piston inlet (9) in the course of the second flow path is routed by a first piston outlet that is provided on a piston end side that faces away from a piston base (10), and a flow throttle (12), a flow regulator (11), or a return flow preventer is provided in the first piston outlet.
