A regeneration valve for a hydraulic circuit may include a valve element for controlling flow between first, second, and third ports. The valve element may be formed with a flow slot that generates a slot flow force when hydraulic fluid flows therethrough. The flow slot may be configured so that a predetermined fluid low rate may generate a slot flow force sufficient to actuate the valve element from a first position to a second position. In the second position, the valve element may divert a portion of flow from the second port to the first port is diverted to the third port. The flow slot may be configured so that the fluid exits the slot at an exit angle that varies as the valve element moves between first and second positions, thereby to provide a more uniform flow force across the range of travel of the valve element. |
