In the regenerative circuits, the fluid in the rod side of the cylinder is sent to the piston side of the cylinder, regenerating the fluid usually destined to the reservoir. This way, in the piston side, the flow arriving from the rod side is added to the flow arriving from the pump, with a notable increase of the piston speed

This solution is utilised to control cylinders when a lower output stroke time is required without increasing the pump flow.

The valve consists of a pilot-operated relief valve and a check valve. When the actuator is moving in the desired direction, the overcenter valve allows fluid flow with minimal resistance, allowing the actuator to move freely. However, when the load or actuator tries to move in the opposite direction, the valve will restrict or block fluid flow, creating a counterbalancing force that opposes the undesired motion.
