Every hydraulic system has a minimum number of basic components, regardless of its design and function. The fundamental components of the hydraulic system include the pump, reservoir, distributor, check valve, pressure relief valve, selector valve, actuator and filter. Say no to plagiarism.

The pump disperses fluid from the reservoir through the selector valves and returns to the reservoir. The open center system can engage multiple subsystems, with a selector valve for each subsystem. The selector valves of the open center system are connected in series to each other. In this arrangement, the system pressure line will pass through each selector valve. Fluid can pass freely through the selector valve and return to the reservoir until one of the selector valves is ready to operate a mechanism. When one of the selector valves is set to operate an actuator, fluid flows from the pump through a working line to the actuator. When the selector valve is set to this position, fluid flow to the reservoir is blocked. The system overcomes resistance using the built-up pressure and moves the piston from the actuating cylinder, fluid from the opposite end of the actuator will return to the selector valve and return to the reservoir. The operation of the system after actuation of the component depends on the type of selector valve used. Many types of selectors are used with the open center system. One type is both manually engaged and disengaged. The valve is manually moved to an operating position. Then the actuation mechanism reaches the end of the operating cycle and the pump flow continues until the pressure is released by the system pressure relief valve. The relief valve disassembles and allows fluid to return to the reservoir. The system pressure remains at the relief valve setting pressure until the selector valve is manually returned to the neutral position. It reopens the open center flow and allows the system pressure to drop to the line resistance pressure..
