The Quad-Flo Bypass Valve from Tomlinson Industries, of Cleveland, is a four-way, two-position bypass valve made of solid brass, featuring the Teflon “Quad Seal?? to ensure a smooth, positive operating action. A single two-position handle requires an easy 90-degree turn for full service to bypass. This produces a positive seal and protects all internal sealing surfaces from water flow. Designed for quick installations and servicing, the valve is perfect for water softeners, general liquid bypass, diverter systems and solar systems.
