Hydraulic Load Sensing Control

Understanding hydraulic load sensing control. Load sensing is a term used to describe a type of pump control employed in open circuits. It is so called because the load-induced pressure downstream of an orifice is sensed and pump flow adjusted to maintain a constant pressure drop

WORKING PRINCIPLE OF A CHECK VALVE AND ITS TYPES IN HYDRAULIC

Check valves could be fixed independently in a line in hydraulic unit or such valves could also be fixed as integral component of pressure reducing valve, pressure sequence valve. Flowing fluid pressure force will open the check valve while the reverse flow pressure or spring force will close the check valve.

How do I know how much pilot pressure is required to lower a load with a counterbalance valve?

Two areas work to open a counterbalance valve—the relief area and the pilot area. The pilot area divided by the relief area equals the pilot ratio. Reverse flow from port 1 to port 2 is blocked by the check valve until a pilot pressure is sensed at port 3 (pilot) that
