Overview

The purpose of the block and bleed manifold is to isolate or block the flow of fluid in the system, so the fluid from upstream of the manifold does not reach other components of the system that are downstream, then bleed off or vent the remaining fluid from the system on the downstream side of the manifold.

For example, a block and bleed manifold would be used to stop the flow of fluids to some component, then vent the fluid from that component’s side of the manifold, in order to effect some kind of work (maintenance/repair/replacement) on that component.
