The 4-Way Ball Valve Mixing Station is a chemical proportioner for accurately diluting 4 chemical concentrates to required ratios and filling any sized container with diluted, ready-to-use chemical solutions. This venturi injection system uses standard city water pressure (25 - 125 PSI) to draw and blend chemical concentrate into the water stream to create an accurately diluted solution. Ball valve activation allows for hands-free dispensing. Available with separate flow rates for each ball valve to dispense into any sized container or equipment.
