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.

A suction control valve comprising:
- a valve housing defining a cavity therein said housing 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 cooperating therewith for creating a suction across said cavity from said inlet port to said outlet port when said suction control port is closed;
- a bacteria filter secured along the interior perimeter of said valve housing for preventing exposure of said suction control port to bacteria entering said inlet port;
- and
- a splash guard extending along said cavity between said inlet port and said outlet port for substantially preventing liquid passing through said cavity from said inlet port to said outlet port from contacting said bacteria filter.
