In contrast to closed-circuit hydraulic systems, suction filtration is not a recommended filtration method with open-circuit pumps. This is due to the potential for high inlet vacuum to occur.

The hydraulic circuit reacts to an external load and the pump adjusts flow based on system requirements. Load sensing is generally considered a reliable, proven technology.

"Hydraulic Control Valves" describes the three main types of control valves and their functions in a hydraulic system. Control valves control the direction, pressure, and flow rate of fluid as it ...
