Manifold operates on the fluid particles that regulate the flow of the actuators in the hydraulic system. It works like a switchboard in the electrical circuit. Thus it helps in the complete controlled operation that lets you know how much fluid it will carry and in which component.
A hydraulic manifold is a manifold that regulates fluid flow between pumps and actuators and other components in a hydraulic system. It is like a switchboard in an electrical circuit because it lets the operator control how much fluid flows between which components of a hydraulic machinery.
