Abstract
A suction control valve comprising a valve housing defining a cavity and including an inlet port for being connected to a suction tube, an outlet port for being connected to a suction source, and a suction control port for creating a suction across the cavity from the inlet port to the outlet port when the suction control port is closed. The valve preferably includes a bacteria filter secured in the cavity for preventing exposure of the suction control port to bacteria entering the inlet port. A splash guard extends along the cavity for preventing liquid from contacting the bacteria filter or from reaching the suction control port. A suction control port guard is selectively movable to prevent accidental closure of the suction control port.
