ABSTRACT:
A flow control valve (10) is provided including a valve body (20) and a piston (16). The valve body (20) has extending therethrough a longitudinal bore (18) defining a fluid passage (32). The piston (16) is slidably disposed within the bore (18) to vary the flow area of a fluid flow through the control valve (10). The piston (16) has a generally cylindrical body formed from a solid piece of material. The piston (16) contains a longitudinal flow channel (24). The longitudinal flow channel (24) has a varying depth. The piston (16) preferably slides within the longitudinal bore (18) to vary the flow area of the fluid passage (32) such that the fluid flow through the control valve (10) is substantially constant over a selected range of pressure differentials across the control valve (10).
