MODULATING VALVE ABSTRACT A modulating valve includes an inlet passage and a discharge passage, both of which are in communica- tion with an internal cavity associated with the valve body. An actuator arrangement includes a pivoting actua- tor shaft, at least a portion of which is located within the internal cavity. A flow-controlling plug member includes a first portion extending into one of the pas- sages, and a second portion located within the internal cavity. The first portion is provided with guide struc- ture engageable with one or more walls defining the passage, to guide axial movement of the plug member. The second portion of the plug member is interconnected with the actuator shaft. The plug member second portion and the actuator shaft are interconnected in such a manner that pivoting movement of the actuator shaft results in axially inward or outward movement of the plug member within the passage. Flow-controlling structure provided on the plug member controls the amount of fluid dis- charged from the valve, depending on the position of the plug member relative to the passage.
