1. A device, comprising:

  • an inlet fluid line;

    a valve housing including an inlet connected to the inlet fluid line, an outlet, and a fluid volume to allow fluid to flow from the inlet to the outlet;

    an outlet fluid line connected to the outlet;

    a first piece of electroactive material connected to the valve housing; and

    circuitry electrically connected to the first piece of electroactive material to apply a first voltage across the first piece of electroactive material to cause the first piece of electroactive material to have a first shape that does not substantially restrict fluid flow through the fluid volume of the valve housing, and to apply a second voltage across the first piece of electroactive material to cause the first piece of electroactive material to have a second shape, the second shape that at least partially restricts the flow of fluid from the inlet through the fluid volume to the outlet.
