Flow control valves are designed to affect the speed of actuators by changing the cross-section of the fluid flow. The valves provide variable (stepless) speed control of the actuator.
Flow control valves can be divided into:
- throttle valves - at the same cross-section of flow, the fluid flow rate changes due to pressure difference at the throttle point
- flow control regulators - regardless of the pressure difference at the inlet and outlet, at the same cross-section, fluid flow remains unchanged
