1. A valve comprising:
an orifice plate comprising at least one orifice surrounded by an orifice plate seal surface;
a seal plate comprising:
a seal boss having a seal boss surface that faces the orifice plate; and
a pocket that overlays the at least one orifice, the pocket defined by a recessed surface that is surrounded by the seal boss surface and displaced from the seal boss surface along an axis; and
an actuator configured to move the seal plate relative to the orifice plate along the axis to transition the valve between open and closed states,
wherein:
the seal boss surface engages the orifice plate seal surface, surrounds the at least one orifice, and blocks a flow of fluid through the at least one orifice when the valve is in the closed state;
the seal boss surface is displaced from the orifice plate seal surface and does not block a flow of fluid through the at least one orifice when the valve is in the open state; and
the seal boss is non-circular.
