The 1-Way Ball Valve Mixing Station is a chemical proportioner for accurately diluting a chemical concentrate to the required ratio and for filling any sized container with diluted, ready-to-use chemical solution. This venturi injection system uses 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 several flow rates to dispense into any sized container or equipment.
