Completely corrosion-free, and molded in luxurious finish, the Vari-Flo is an efficient, positive sealing control valve for all filtration applications. It will retrofit any filter that has an SP071113 valve that needs replacement and upgrading. All control valves feature an easy-to-use lever action handle that lets you "dial" up to six valve/filter functions: filter, backwash, waste, rinse, closed or recirculate. Complete with an integral sight glass that lets you see when the backwashing cycle is completed, our wide selection of valve configurations allows you to match the right Vari-Flo valve to the proper application; residential, commercial, top-mount or side mount.
