A mixer valve (1) comprises a body (5) extending in a first direction between a front end and a rear end. The body (5) defines a volume (5a); a thermostatic cartridge (15) is received in the volume (5a), and a diaphragm valve (21) is received in the volume (5a) between the thermostatic cartridge (15) and the rear end of the body (5). The diaphragm valve (21) is operable in response to actuation of a push operated control member (23) to control flow of water from the mixer valve (1).

A method of controlling actuation of a flush apparatus includes the steps of configuring a control module to actuate the flush apparatus for completing a flushing cycle periodically; and after a given unused time period of the flush apparatus, enabling the control module to enter into a sleep mode to stop an actuation of the flush apparatus. Therefore, during the rush hours, the control module is configured to actuate the flush apparatus frequently and during the off rush hours, the control module is configured to actuate the flush apparatus seldom.

A flush valve assembly has a pilot valve and a drive train for selective driving the pilot valve between an open position and a closed position. The drive train has a drive gear coupled to a motor for rotating the drive gear and a valve gear coupled to the pilot valve and intermeshing with the drive gear. At least one of the drive gear and the valve gear have a flag extending outwardly therefrom. A sensor positioned to detect the flag and establish a rotational position of the drive gear and the valve gear to thereby establish an opened or closed position of the pilot valve.

A method for controlling a speed of a hydraulic cylinder (2) in a hydraulic system (1) is provided. The hydraulic system (1) may include a hydraulic cylinder (2) fluidly connected to a load-holding valve arrangement (3) including a first load-holding valve (4) connected to a first end (5) of the hydraulic cylinder (2) and a second load-holding valve (6) connected to a second end (7) of the hydraulic cylinder (2). The hydraulic system (1) may further include a flow-control valve arrangement (8) comprising a directional flow-control valve (9) and at least one hydraulic pump (10).

A faucet includes a faucet housing defining a mixing chamber and a dry chamber, a valve assembly, and a damper assembly. The valve assembly includes a main shaft having a first end and a second end, a knob coupled to the first end, a mixing plate coupled to the second end, a main seal coupled to the main shaft, and a first biasing member disposed around the main shaft. The first end is disposed within the mixing chamber and the second end is disposed within the dry chamber. The damper assembly includes an outer cylinder disposed within the dry chamber, a piston extending at least partially into the outer cylinder, and a second biasing member disposed within the outer cylinder. The piston has an interference surface configured to contact the knob, and the second biasing member is configured to bias the piston.

A playground water feature including a feature outlet. The playground water feature also including a diaphragm valve configured to receive water flow from a water source. The playground water feature also including a mechanical activator, configured to, when actuated, open a vent valve, that is fluidically coupled to the diaphragm valve, such that the diaphragm valve opens to allow the water flow to flow to the feature outlet.

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.
