= CONTROLE PLATE FOR A HIGH CONDUCTANCE VALVE =

'''Abstract''':
a high purity control valve for use in high conductance, proportional control applications includes a moveable control plate having a flow-through passage to enhance fluid sweep of the internal valve volume. nested orifice ridges are used to achieve high conductance with small actuator movement. enhanced leak tightness can be provided by incorporating into the control plate materials softer than the material comprising the orifice ridge. the control plate comprises a control plate body having a counterbore in fluid communication with a conduit, radial fluid flow paths and axial fluid flow paths. a flat side of the control plate includes a continuous uninterrupted flat portion to shut-off fluid flow in the valve. the radial fluid flow paths provide fluid communication from the counterbore to a circumferential perimeter of the control plate and the axial fluid flow paths provide fluid communication with the fluid conduit through an intermediate valve chamber portion.
