Sprinkler valve sizes. For residential use, the most common sizes are 3/4-inch and 1-inch—that is, they fit those sizes of sprinkler pipes, so the size you choose will depend upon your system’s design. A 1-inch valve handles a heavier water flow than a 3/4-inch valve. Sprinkler ...
This invention provides for a valve system for use in fire suppression systems that provides pressure relief, pressure testing, and drain/test fluid flow capability. The valve system consists of a valve body with an attached riser. Adjustably attached to the riser is a rotary handle for raising...
A plurality of irrigation sprinklers are sequentially operated for timed intervals by an electrical control system having a timing mechanism through which valve solenoids are energized. Selected solenoid circuits are opened by eliminator switches to bypass desired sprinkler locations during timed irrigation ...
