The valve is threaded onto the pot filler faucet and is opened and closed by turning of the hand wheel secured to the nozzle either clockwise or counter-clockwise. The ceramic valve discs within the valve have pairs of passages that provide either opening or closing of the valve for each 90° turn of the hand wheel. A spring actuated plunger between the valve body and the rotatable nozzle provides an audible sound when moved into a recess in a flange of the nozzle.
