An addition of a fine adjustment flow-control mechanism that produces changes in fluid flow in increments of 0.1% or less, to any configuration high pressure fluid flow control valve that employs an axial valve stem and a rotatable rough control knob that moves the stem axially in increments of 1.0%

An addition of a fine adjustment flow-control mechanism that produces changes in fluid flow in increments of 0.1% or less, to any configuration high pressure fluid flow control valve that employs an axial valve stem and a rotatable rough control knob that moves the stem axially in increments of 1.0% or more, opening the valve flow chamber to fluid flow. The valve stem is designed and driven so that it does not rotate or twist, and provision is made to minimize control drive tolerance build-up. These aspects produce a high degree of adjustment accuracy during operation of the flow control valve.
