An apparatus for simultaneously, separately dispensing a multiple of fluids. The apparatus includes a chamber with a plurality of fluid inlets and a fluid outlet corresponding to each fluid inlet. A plunger is linearly movable in the chamber and has a plurality of spaced apart heads movable into blocking relationship between corresponding fluid inlet and outlet ports, and out of blocking relationship between corresponding fluid inlet and outlet ports to provide isolated fluid passages through the apparatus between corresponding inlet and outlet ports allowing coordinated movement of a plurality of different fluids through the apparatus. The heads and ports may be relatively sized and spaced to provide either simultaneous initiation and termination of multiple fluid discharge or staged initiation and termination of fluid discharge.
