A mechanical component that regulates the direction of fluid flow in hydraulic systems is called a Torque sectional directional control valve. Another name for them is switching valves. It has unique design of working, inlet and outlet sections, which can be replaced as per requirement.
Directional control valves come in three main categories:
Hydraulic check valves
Directional spool valves
Poppet valves
