What is the primary function of the flow control valve?

The main idea is that this valve is there to control how fast hydraulic fluid moves through the system. A flow control valve meters or throttles the flow, setting the actuator’s speed by limiting the amount of fluid that can pass per unit of time. It often uses a needle or adjustable orifice to achieve the desired flow rate, and some designs even compensate for pressure changes to keep the flow steady. It doesn’t raise system pressure (that’s done by the pump or a pressure relief valve), it doesn’t filter contaminants (that’s a filter), and it doesn’t store hydraulic fluid (that’s a reservoir).
