Abstract
An self-regulating quarter turn faucet valve is fabricated entirely of non-metal parts for use in purified and distilled water dispensing faucets. The valve has wall dimensions that are designed to withstand the torque and tensile forces generated when the valve is threaded into a faucet receptacle and has key operational components located in non-stressed areas of the valve to prevent destructive shear forces during operation. A stacked polished ceramic disc arrangement is used to shut the valve on and off through rotation of the discs relative to each other to align and misalign wing-shaped openings formed in the discs.
