Abstract
A valve with an integral bleed passage includes a valve body including a threaded bore, a bonnet having a first threaded portion arranged to be securable to the bore of the valve body and having a second portion disposed outside the valve body, and a cavity defined between the valve body and the first portion of the threaded bonnet. A bleed passage is formed in the bonnet and includes an entrance aperture formed in the first portion of the bonnet and in flow communication with the cavity, the passage including an exit aperture formed in the second portion of the bonnet, and a main portion providing flow communication between the entrance aperture and the exit aperture. The cavity and the entrance aperture are positioned to expose the passage to an interior portion of the valve prior to removal of the bonnet from engagement with the valve body.
