1. A system for mixing and delivering fluids, comprising:

  • at least two fluid sources;

    a pump;

    a joining fluid path connecting the at least two fluid sources to an inlet to the pump; and

    a valve device in the fluid path upstream of the pump and comprising an actuator adapted to restrict flow in at least one of respective fluid lines connecting the at least two fluid sources to the pump inlet; and

    wherein the valve device actuator is adapted to restrict flow in at least one of the respective fluid lines such that an incremental positional change in valve device actuator position provides a substantially linear change in fluid mixture ratio of the at least two fluids from the at least two fluid sources to the pump inlet.
