Abstract
An externally adjustable restriction control assembly for a poppet valve. The restriction control assembly is actuated through rotation of the valve stem. Upon rotation of the valve stem, a restriction control disc, threadably mounted to the valve stem guide, is moved toward or away from a seat provided within the housing. Movement of the restriction control disc thereby adjusts the effective cross-sectional flow area through the valve.
