2-Way Ball Valve SS Mixing Station

Model # 985200SS

The 2-Way Ball Valve SS Mixing Station is a solvent-resistant chemical proportioner for accurately diluting two chemical concentrates to the required ratio, or achieving to different ratios of the same chemical, and for filling any sized container with diluted, ready-to-use chemical solution. This stainless steel 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.

Key Features
  • Eliminates manual mixing and optimizes chemical utilization, employee safety and labor efficiency
  • Ball valve activation allows for hands-free dispensing
  • Stainless steel injector body and solvent-resistant wetted components ensure durability and years of outstanding performance with minimal maintenance
  • Water pressure gauge eliminates guessing, reduces set-up time and helps with troubleshooting
  • Dilution ratio controlled with precision metering tips
  • The dilution ratio for each valve is set independently
  • Draws chemical concentrate from any sized container
  • Choice of left or right side water inlet
  • Choice of flow rates for filling small to large containers
    • Please specify the flow rate for each valve when ordering
