Abstract
A material regulating valve which controls the flow of an additive material into a primary material as a function of the volume, flow rate, and viscosity of the primary material. The device is comprised of a two sectioned body with a primary flow path and an additive flow path through the body such that the additive flow path intersects the primary flow path at one portion in the body. Located between the primary flow path and the additive flow path is a additive flow regulating component. The device also included a flow indicator which provides a visual confirmation when material is flowing through the primary path and a manual control component which provides a manual over ride of the normally self controlling flow regulating component.
