Flow-control valves include simple orifices to sophisticated closed-loop electrohydraulic valves that automatically adjust to variations in pressure and temperature. The purpose of flow control in a hydraulic system is to regulate speed.
Flow rate also determines rate of energy transfer at any given pressure. There are eight types of flow-control valves: Orifices, Flow regulators, Bypass flow regulators, Demand-compensated flow controls, Pressure-compensated-variable flow valves, Pressure- and temperature-compensated, Priority valves And Deceleration valves.
