摘要： A process for the treatment of brass components to reduce leachable lead therefrom when the component is exposed to water in which the brass component is first treated with an aqueous caustic solution to remove some of the leachable lead therefrom. Thereafter, the brass component is leached to remove excess caustic and then contacted with a water soluble carboxylic acid to remove most of the remaining leachable lead. It has been found that the efficiency of the process can be significantly enhanced through the use of ultrasonic agitation to ensure intimate contact between the treating solutions and the brass component. In the practice of the invention, the amount of lead removed is sufficient to meet the most stringent regulatory requirements for water quality.

摘要： A diverter valve (10) for selectively controlling the flow of fluid from a fluid source to one of several fluid outlets (132, 136) includes a fixed ceramic disk (14) fixed to a housing (12) and a rotating ceramic disk (16) retained in the housing against the fixed disk by a retainer (24). An accessory mount (20) is adhered to the rotating ceramic disk to facilitate connection to accessories and to direct fluid from the valve. Flow passages (88, 90, 104, 106, 108, 110, 112) in the disks cooperate with flow passages (54, 64, 66, 68) in the housing and flow passages (116, 118, 122) in the accessory mount to balance the pressure of fluid flow within the valve against the disks to minimize leaks and prolong durability.
