  • Patent number: 11946234
    Abstract: A control valve for at least one sanitary fitting that contains a body having at least one inlet (3) for a liquid; a diaphragm valve for opening and closing a flow channel of the control valve, the diaphragm valve having a diaphragm and a counterpressure chamber connected to the at least one inlet, and a pilot orifice being formed in the diaphragm, which pilot orifice connects the counterpressure chamber to the flow channel; a multi-port valve disposed downstream of the diaphragm valve and having a plurality of outlets for the liquid; and a controller for controlling the diaphragm valve and the multiport valve, the controller containing a control rod extending through the pilot orifice of the diaphragm, wherein the control rod can be adjusted in a longitudinal direction for controlling the diaphragm valve and can be rotated for controlling the multiport valve.

  • Patent number: 11821541
    Abstract: A valve (1) for a sanitary faucet, comprising: a liquid duct (2) having at least one inlet (3) and at least one outlet (4) for a liquid; a diaphragm valve (5) having a diaphragm (6) and a counterpressure chamber (7) connected to the at least one inlet (3); and a control rod (8) for controlling the diaphragm valve (5), wherein a push button (9) can be used to adjust the control rod (8) between a closed position, in which the diaphragm valve (5) is closed, and an open position (10), in which the diaphragm valve (5) is at least partially open, wherein a rotary handle (11) can be used to adjust the control rod (8) in the open position (10) between a minimum flow position (12), in which a minimum flow rate of the liquid flows through the at least one outlet (4), and a maximum flow position (13), in which a maximum flow rate of the liquid flows through the at least one outlet (4), and wherein the minimum flow position (12) of the control rod (8) can be variably adjusted.

  • Patent number: 11112030
    Abstract: A valve cartridge for a sanitary fitting having a cartridge housing, a valve stem which is rotatable about an axis of rotation relative to the cartridge housing, a handle for rotating the valve stem, a passage disk with a first passage and a second passage, a control disk rotatable with the valve stem for controlling a liquid flow through the first passage or the second passage of the passage disk, a handle adapter which can be connected to the valve stem for setting a first rotational orientation of the valve stem to the handle in a first position and can be connected to the valve stem for setting a second rotational orientation of the valve stem to the handle in a second position, so that the control of the flow of liquid through the first passage or the second passage can be changed by the control disk.

  • Patent number: 10458567
    Abstract: A process medium-controlled regulating valve for a liquid throughflow regulator, having a main valve, a pilot valve for controlling a main valve piston, a pilot valve piston which closes the pressure relief line in a closed position, a cleaning wire element which is stationary in the axial direction is guided with hole tolerance through the pilot line, and the pilot line can be moved along the cleaning wire element, which is guided therein, during a stroke adjustment of the main valve piston. The cleaning wire element has an actuating contour which, at least during the stroke adjustment, can be brought into sliding contact with a counter-contour formed on the main valve piston, with the build-up of a transverse force which acts on the cleaning wire element.
