OPERATION

When oil enters the ‘A’ port, it is first directed toport ‘A1’. When the pressure at ‘A1’ reaches the valve setting, oil is directed to port ‘A2’. In the opposite direction of oil flow, oil entering port ‘B’ is first directed to port ‘B1’, and then to port ‘B2’. Oil returning from the actuators flows freely. Full pressure is available to both actuators once the valve settings have been reached.
