Abstract
A valve includes an orifice plate including at least one orifice surrounded by an orifice plate seal surface, a seal plate, and an actuator. The seal plate includes 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 includes a recessed surface that is surrounded by the seal boss surface and is displaced from the seal boss surface along an axis. The actuator is configured to move the seal plate relative to the orifice plate along the axis to transition the valve between open and closed states. 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.
