What Is a Block and Bleed Valve?

Block and bleed manifolds, or block and bleed valves, are isolation valves containing a single block valve and a single bleed valve. Block and bleed needle valves can be very useful for controlling flow in a wide variety of industrial applications, such as in combustible gas trains or various hydraulic systems.

Similarly, as defined by the American Petroleum Institute, double block and bleed valves contain a single valve but have two seating surfaces that, when closed, seal against pressure from both ends of the valve. They're commonly used in the oil and gas industries but can be used in nearly any application in which you need to isolate pipes for maintenance or bleed the valve cavity.
