What is a Directional control valve?

A directional control valve is a valve that controls the direction of hydraulic fluid flow in a hydraulic circuit. Controls the movement of cylinders, motors, etc. If the hydraulic actuator is a cylinder, it determines the telescopic direction, if it is a motor, it determines the rotational direction, and if it is a grab-type attachment, it determines the cloud-dump direction. Directional control valves are mainly check valves (check valves) and directional switching valves. There are mechanical, hydraulic and electromagnetic control methods for directional control valves. With the advent of the electromagnetic type, the convenience of control has improved.
