Abstract: Described are water-on-water valves for use in reverse osmosis filtration systems. The water-on-water valves are regulated by the pressure in a product line, which contains fluid from a product line of the filter module and/or the product side of a water-on-water storage tank. Exemplary valves are shuttle valves that are regulated by the pressure downstream of the product side of a reverse osmosis filter module. The valves may comprise a piston within a housing, and an end of the piston may have an enlarged diameter relative to the maximum diameter of the remainder of the piston. The body of the piston may have sections of differing diameters, where the smaller diameter sections form flow channels, or the body may a diameter that is substantially the same along its length in conjunction with gratings and flow channels.

Abstract translation: 描述了用于反渗透过滤系统的水上水阀。 水上水阀由产品线中的压力调节，产品线包含来自过滤器模块的产品线和/或水包水储罐的产品侧的流体。 示例性的阀是通过反渗透过滤器模块的产品侧下游的压力调节的梭阀。 阀可以包括在壳体内的活塞，并且活塞的端部可以具有相对于活塞的其余部分的最大直径的增大的直径。 活塞的主体可以具有不同直径的部分，其中较小直径的部分形成流动通道，或者主体可以与光栅和流动通道一起沿其长度基本上相同的直径。
