A plural component mixing system includes an automatic balance feature to balance the pressure of two or more components as they are mixed. The pressures or flow rates of the two components are monitored. If there is a difference in pressure or flow rate greater than a specified amount, a bleed valve is opened for a short period of time to balance the flows. A computer with a touch screen is used to set the pressure and flow rate differences that trigger the bleed, and to set the time period for the bleed.
