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 special control valves for log splitter machines with automatic kick out feature.

P81 RS features an extremely fast “rapid extend” high speed mode. The P81 RS has been designed to reduce system cost by allowing a single stage pump to be used in systems currently using two stage (hi-low) pumps. When extra force is required,  the user can manually shift from high speed mode to high force mode. A “soft stop” differentiates between high force and high speed modes.
