ABSTRACT:
A pneumatic control valve (10) including a valve body (12) with fixed aperture plate (14), a movable redirector (18) and a force motor (26). The force motor (26) supports the redirector (18) adjacent to the aperture surface (16) of the fixed aperture plate (14) and is operable to move the redirector (18) back and forth along a line (28) without contacting the aperture surface. The aperture surface (16) has a plurality of apertures (70,72,74,76,78) with metering edges (124,126,128,130,132,134,136,138). The redirector (18) has redirector cavities (102,104,106,108) with metering edges (140,142,144,146). The force motor (26) deflects the redirector (18) to positions in which one or more of the cavities in the redirector connect two or more of the apertures (70,72,74,76,78) and direct fluid from some apertures and into other apertures. The location, length and shape of the metering edges can be varied as required to obtain desired fluid flow characteristics.
