Abstract: In order to simplify the operation of a valve assembly (2) which includes a plurality of valves (3) that have respective activating elements (8) which serve for in each case manually opening the valves (3), the activating elements are temporarily blocked with the aid of at least one shut-off part (6) so that an activation of at least one of the other valves (3) of the valve assembly (2) is currently precluded.

Abstract: To improve the operating characteristics of an actuation device for activating water paths of a sanitary installation, the actuation device has a locking mechanism (22) based on at least one movable locking element (23), by which locking mechanism at least two actuation elements (8) of the device that are used to actuate associated valves (3) can be releasably locked in respective actuation positions. The actuation device has a separate releasing actuation element (4), by which the locking of each of the other at least two actuation elements (8) can be released.

Abstract: In an actuation apparatus (7) which is configured for actuating a valve arrangement (8), there is provision for the actuation elements (9) for a valve (10) each to be arranged at the corners of a convex polygon (11) with three or more corners.

Abstract: In order to improve the operating properties of an actuating device (1) for opening water routes (53) of a sanitary installation (52), the actuating device (1) has a locking mechanism (22) having at least one movable locking element (23), by way of which locking mechanism (22) at least two actuating elements (8) of the apparatus (1) which serve to actuate associated valves (3) can be locked releasably in a respective actuating position (30). The actuating device (1) also has a separate release actuating element (4), by way of which a locking state of each of the remaining at least two actuating elements (8) can be released.

Abstract: The disclosure relates to a valve having an inlet device, which has at least one inlet opening and at least one outlet opening, and having a closing device for opening and closing the at least one inlet opening and/or outlet opening. The valve has an actuation device for actuating the closing device. The actuation device is guided in an axially moveable manner in a first direction in a housing. The valve further has a coupling element, which connects the actuation device and the closing device to one another such that an axial movement of the actuation device causes a movement of the closing device in a second direction that differs from the first direction.
