Abstract
A unified block integral bleed system for use with valves such as plug-type valves wherein pressure release flow occurs through a manifold port mounting arrangement which accesses upstream, downstream and body cavity portions of the valve and provides atmosphere taps as well without external piping. Such a manifold integral body bleed system provides internal flow channels and is preferably configured as the bonnet of the valve but could also be configured for example as the lower plate of the valve. In fact, any valve component which provides inherent access to the upstream and downstream throats and the central body cavity could serve as the bleed system manifold component as well.
