Abstract:
The present device relates to an apparatus and method for automatically sequencing the flow of fluid between one fluid source and at least two fluid chambers in response to an interruption of fluid flow or pressure. Particularly, the device relates to irrigation. In its preferred embodiment, the apparatus is a sequencing valve that includes a two-sided flapper valve that is controlled by a spring and piston mechanism in order to direct fluid flow between chambers. In an alternate embodiment, the device includes a mechanism that also allows manual sequencing of fluid flow.
