Hydraulic System Working Principle. The working principle of a hydraulic system is based on the transmission of force through a pressurized fluid. A hydraulic system consists of a pump, a fluid reservoir, and a system of tubes and valves that control the flow of fluid. Here is a summary of the working principle of a hydraulic system:
There are four major valve types: ball valves, butterfly valves, globe valves, and plug valves. There is also an array of many other types of valves specific to certain processes. Selecting which type of valve to use depends on what task the valve must carry out and in what space said valve can fit to carry out the task.
This, coupled with the fact that the working principle of the valve requires constant internal pressure, means that parasitic loss is constantly occurring, undermining the efficiency of these valves.
