A flowgrid regulator for use as a flow control device in conjunction with a pilot system. The invention includes a valve body, containing a flow barrier, that connects to a spring casing with a throttling plate, spacer and diaphram sandwiched therebetween. The throttling plate intersects the barrier and includes openings on either side of the barrier intersection for passing a flow under pressure therethrough. The diaphram is constructed of a non stretchable flexible material and is maintained to move vertically above the throttling plate to position a throttling element bonded thereto into covering engagement with the throttling plate openings. The diaphram position is controlled by a combination of spring force and pressure differential as supplied by the pilot system connection thereto to urge the throttling element against the throttling plate openings thereby controlling flow area and now rate. |
