Abstract
A fine control gas valve is disclosed. The valve has a tee having first and second tee runs co-axially aligned on a longitudinal axis, and a tee branch oriented non-parallel to the longitudinal axis. A rotatable hand operator member cooperates with a threaded member and a sleeve to enable a valve to be adjustably positioned within the tee. Indicia on the valve may be used to help a user understand how a fluid flow through the valve will be affected by adjustments made by the rotatable hand operator member.
