Tomlinson Industries’ Quad-Flo™ bypass valve is a four-way, two-position valve made of solid brass featuring a Teflon® “Quad-Seal™?? to ensure a smooth, positive operating action. A single two-position handle requires an easy 90° turn for full service to bypass. Designed for soft solder and threaded installations, the Quad-Flo bypass valve is available in ¾?? and 1?? connections. Quad-Flo bypass valves are the superior choice for water softeners, general liquid bypass, diverter systems and solar systems.Email: gstrunak@tomlinsonind.comWebsite: http://www.tomlinsonind.com
