Proportioning valves used for Buffer Blending and inlet selection. Each valve has
two inlet ports and one outlet port. For Buffer Blending, acid is placed at inlet A1,

connected directly to their respective Workstation pump inlet ports. Color-coded
tubing is supplied with the Maximizer for plumbing the inlet ports (A1 = red, A2 =
blue, B1 = yellow and B2 = green).
