A mixing valve having a mixing passage formed by a tapered concentric reduction member for forming a venturi, a pair of baffles supporting the reducing member to form a mixing chamber where liquid from secondary inputs is metered by the venturi into an axial flow of liquid. The mixing valve is particularly adapted for use with a method of hydrating concentrated polymer and mixing in recycled polymer from an eductor. The method includes passing water through a venturi, metering a flow of neat polymer and a flow of recycled polymer from the eductor into the mixing chamber by the venturi effect.
