Abstract: A solenoid valve system includes a valve body defining porting for a fluid flow through the valve body, and first and second solenoid valve components attached oppositely to the valve body. Each valve component includes an electromagnetically driven armature with a poppet that moves between a closed position and an open position. The porting defined by the valve body includes first side porting, second side porting, and common porting in fluid communication with an internal common chamber defined by the valve body. When a respective poppet is in the closed position, flow of fluid is blocked between the respective side porting and the common porting, and when the respective poppet is in the open position the poppet permits a flow of fluid between the respective side porting and the common porting through the common chamber.

Abstract: An example control unit may include: a processor; an output device; a valve element; an actuator; and a sensor for the position of the valve element. The valve cycles and the processor records a first signal to measure a position of the valve element. The valve cycles and the processor records a second signal to measure a position of the valve element. The processor calculates a degree of wear based on the first value and the second value and the second number of valve cycles. The processor compares the degree of wear to a predefined threshold value and generates an output signal if the degree of wear exceeds the predefined threshold value.

Abstract: A water delivery system is provided, including at least one sink with a faucet device having a cold water faucet part and a hot water faucet part, a cold water line to the at least one sink, a hot water line to the at least one sink, and a valve associated with the at least one sink allowing in an open state the transport of water between the hot water line and the cold water line and inhibiting in a closed state the transport of water between the hot water line and the cold water line, wherein the open state and the closed state of the valve depend solely on whether a differential pressure across the valve is below or above a threshold value.

Abstract: The cartridge comprises a slide valve for regulating the temperature of a mixture of hot and cold fluids. The slide valve is, under the action of a thermostatic element and in relation to an outer casing of the cartridge, which can be displaced along the central axis of the casing in such a way as to vary inversely the respective flow sections of an inlet for a first of the fluids, delimited axially between the casing and one of the two opposite axial surfaces of the slide valve, and of an inlet for the second fluid, delimited axially between the casing and the other axial surface of the slide valve. Therefore the cartridge can, effectively and economically, provide a good mixture of the two fluids, a flow passage.

Abstract: A single lever valve for mixing hot and cold liquids has a mixer which can internally impose an upper limit on the temperature of any liquid emerging from it. The means used may enable the upper limit to be changed by exchange of a component so that the mixer can be used in any location in an installation even though different locations might have different upper limit requirements. The mixer may take the form of a cartridge able to be exchanged with an existing cartridge to convert an “unsafe” mixer to a “safe” one.

Abstract: A temperature controlling valve serves to adjust a mixed rate of cold and hot waters to control a temperature of the mixed cold and hot water by using a water supplying means having a first pore to flow the cold water, a second pore to flow the hot water, a first shield to close the first pore, and a second shield to close the second pore; wherein when the temperature control set is driven by a driving motor to rotate at an original position, the first and the second shields are actuated to close the first and the second pores so that the cold and the hot waters flow into a valve core to be mixed together, wherein an inverse relationship exists between the cross sectional area of the first pore to flow the hot water and the cross sectional area of the second pore to flow the cold water.

Abstract: The cartridge comprises two ceramic disks (20, 24) for regulating the temperature and flow of a mixture (M) of two entering fluids. In order to ensure that the temperature of the mixture remains lower than a predetermined value, the cartridge comprises thermostatic means (16) designed for, in the event of a high-temperature mixture, automatically shutting off, upstream from these disks, the circulation of the entering fluid (C) of the highest temperature.

Abstract: Thermostatic mixing valves and systems for mixing fluids of dissimilar temperature are disclosed. A thermostatic mixing valve in accordance with an illustrative embodiment of the present invention can include an elongated valve body defining a cold fluid inlet, a hot fluid inlet, a mix fluid outlet and a mixing chamber, a fluid flow regulator for adjusting the flow of cold and hot fluid injected into the mixing chamber, and temperature selection means for adjusting the temperature of fluid contained within the mixing chamber. The valve body may have a vertical, in-line configuration wherein the hot fluid inlet, mixing chamber, and mix fluid outlet are substantially axially aligned along a vertical longitudinal axis of the valve body, allowing hot fluid to pass substantially vertically through the valve body towards the mix fluid outlet.

Abstract: An automatic compensating valve, e.g., for individual shower and tub/shower combination fixtures, has a valve body defining cold and hot water inlet flow passageways, a mixing chamber, a mixed temperate water outlet flow passageway, and an axial bore. The valve includes a plunger that defines, with other elements of the valve, a first orifice for communication of the cold water inlet with said mixing chamber and a second orifice for communication of hot water inlet with mixing chamber. The plunger is mounted within a mixing subassembly for axial movement within the bore, including in response to temperature of water within the mixing chamber to vary the ratio of flow of cold water through the first orifice to flow of hot water through the second orifice. The first orifice and the second orifice are arranged for flow of water transverse to axial movement of the plunger within the bore.
