A flush valve according to the present disclosure includes a pressure compensating device for toilet and urinals to ensure consistent flush and bowl refill volumes. Certain flush volume limits may required for compliance with federal, state and local regulations regarding water usage. The flush valve can adjust water flow rates within the prescribed water usage limits and does not sacrifice the toilet's bowl washing and waste removal capabilities.

The present invention provides an in-line valve cartridge for use in sanitary fittings. The valve cartridge of the present invention includes a generally cylindrical housing having a proximate extent for support in a sanitary fitting, a distal extent from which water leaves the cartridge and a longitudinal body extending therebetween. The body has a thickness delineated by inner and outer peripheral surfaces with the inner peripheral surface further defining an elongated lumen thereby. The housing further includes an annular aperture that accommodates placement of a driving member therethrough and includes opposing extents that operate as stops for the driving member and correspond to the valve cartridge's open and closed positions. In addition, rotating and stationary ceramic disks are disposed in tandem wherein the stationary disk has at least one aperture for through flow of cold water, hot water or a combination thereof. At least one protrusion depends outwardly from a portion of the inner peripheral surface adjacent the proximate extent so as to define at least one each of a corresponding proximate seat and a distal seat therein. The proximate and distal seats support an additional valve element in the lumen. A piston is disposed in communication with the driving member such that translational movement of the driving member along the annular aperture imparts rotational motion to the rotating disk, thereby effecting linear fluid flow through the piston and consequently through the cartridge.

A filtration cartridge faucet assembly contains a filtration cartridge having a filter core that is concealed beneath a sink deck through the use of an escutcheon mount. The escutcheon mount permits access to a renewable filtration cartridge from above the sink deck while concealing and protecting the filtration body. The renewable filtration cartridge is equipped with a flow control device, as well as counter rotation devices that prevent undesirable outrotation of a threaded cap.
