Has anyone used one of these guys, such as the six zone distribution valve shown below in the picture? By turning the power on and off to the valve you can sequence the outlet from port 1, to port 2, and so on. With a controller's multiple start times for a zone you could use this one valve in place of six. My idea was to use one for a number of drip zones. I could get by with just one regulator, and one filter. The idea of using one valve for numerous zones sounds entertaining, but has anyone been down this road?
