ABSTRACT:
An improved hydraulic flow-control valve with critical dimensional characteristics which assure laminar flow rather than turbulent flow through the valve thus reducing or eliminating valve "hunting" or chattering and increasing sensitivity of the valve to pressure changes and assuring accurate and totally predictable fluid flow control over a wide range of differential pressures across the valve.
