• Meter-in circuit is a method by which a flow control valve is placed in a hydraulic circuit in such a manner that there is a restriction in the amount of fluid flowing to the actuator.
• If the flow control valve were not to be located, the extension and retraction of the actuator which in this case is a cylinder, would have proceeded at an unrestricted rate.
• The presence of the flow control valve enables restriction in the fluid flow to the cylinder and thereby slowing down its extension.
• In the event of the flow direction being reversed, the check valve ensures that the return flow bypasses the flow control valve.
• The inlet flow into the cylinder is controlled using a flow-control valve. In the return stroke, however, the fluid can bypass the needle valve and flow through the check valve and hence the return speed is not controlled.
• This implies that the extending speed of the cylinder is controlled whereas there tracing speed is not.
