The check section allows free flow from the directional valve (port 2) to the load (port 1), while normally blocking flow from port 1 to port 2. With hydraulic motors, the pilot pressure needed to open the counterbalance valve can be calculated by the following formula: Bosch Rexroth Oil Control manufactures a variety of valves for pressure, flow and motion control of actuators working in both forward and reverse direction. Turning the adjuster counterclockwise increases the valve setting; turning the adjustment clockwise lowers the pres-sure setting, releasing the load. 15 mm If a standard counterbalance valve is applied in this situation, it would open but then immediately close when pressure builds up against the directional valve.
