Directional control valves are one of the core elements in a hydraulic circuit. They help directing the fluid to different components in the system.

Directional control valves perform only three functions:

  1.   Stop fluid flow
  2.   Allow fluid flow
  3.   Change direction of fluid flow

There is a part called «spool» inside control valve which can be operated mechanically or electrically. The movement of the spool lets oil flow or blocks the oil flow in other words it controls the movement of fluid. Hidros provide electro hydraulic directional control valves with different capacities and spool types.
