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 preferrably configured as a separate external unit which can be retrofitted to existing valve installations in the field. The manifold bleed system may be attached to the valve, such as by welding, or may be located at a position remote from the valve.
