Abstract
An Automatic fluid component Shut Off System which automatically shuts off the flow of one component in a plural component system when the pressure in another component falls below a predetermined amount. The system is comprised of pneumatically operated sources of fluid components such as a catalyst and a resin which are mixed as they are sprayed on an article. The automatic shut off system is comprised of a pressure sensing valve which is connected to one of the components to provide a pressure control point and controls the supply of air to an air operated servo valve controlling the flow of the other fluid component. The pressure control point is established by adjusting an air pressure regulator connected in series with the pressure sensing valve.
