FLEX-ING™ brand ball valves provide in-line product flow shutoff, making testing and inspection of equipment easy. Incorporating ball valves into the installation of your pipework system up front can save you on time, labor and dispenser shutdown costs for years to come. The use of ball valves allows you to isolate and shut down the flow of product to specific system components so you can perform maintenance or inspection on only the desired components, while the rest of the system remains in operation.
