Abstract

See full text

A fine control gas valve includes a tee having opposed first and second tee runs co-axially aligned on a longitudinal axis, and a tee branch. A valve assembly is partially received in and connected to the first tee run having a valve disc connected to a drive screw longitudinally moved by drive screw axial rotation. The valve disc includes a first slot on the valve disc having a first end and a wider second end, and a second disc slot as a mirror image of the first disc slot oppositely positioned about the valve disc. A pipe in the second tee run has a first portion of a pipe end face/seat surface in direct contact with a second tee run shoulder. The valve disc when contacting a second portion of the pipe end face/seat surface defines a valve closed condition. The first and second portions are co-planar to each other.
