Abstract:
A control plate for effecting superior shut-off in a proportional control valve comprises a moveable disk-shaped element that has a flat surface, generally perpendicular to the valve axis of symmetry when closed, and translates toward or away from an orifice surrounded by a narrow lip or orifice ridge. Enhanced leak tightness in the valve shut-off condition is achieved by selectively incorporating into the control plate materials that are softer than the material comprising the orifice ridge.

Claim (Index 1):
A valve bonnet for use with a control valve body, the control valve body having a fluid conduit opening surrounded by a planar orifice ridge, the valve bonnet comprising:\n a bonnet body; a valve diaphragm in sealing engagement with the bonnet body at an outer periphery of the valve diaphragm; a control shaft secured to the valve diaphragm, the control shaft having a shank projecting from the control shaft; and a valve control plate body secured to the shank, the valve control plate body formed from a first material having a first hardness, the valve control plate body having a first surface configured to face toward the fluid conduit opening, the valve control plate body having a recess defined in the first surface of the valve control plate body and a plurality of holes extending through the control plate body within the recess; and a valve seat insert formed from a second material having a second hardness that is less than the first hardness, the valve seat insert having a first surface configured to face toward the fluid conduit opening and sealingly engage the planar orifice ridge, the valve seat insert being molded into the recess and including a plurality of at least one of posts, columns, and bridges formed in the valve seat insert that extend into and fill the plurality of holes defined in the control plate body, and lock the valve seat insert into the control plate body.
