S-290 Monoblock Control Valve
Directional control valves are one of the core elements in a hydraulic circuit. They help directing the fluid to different components in the system. Hidros provide monoblock, sectional, and solenoid-operated spool type control valves with different flow capacities and spool options.

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:
Stop fluid flow
Allow fluid flow
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 solenoid operated on-off directional control valves with different capacities and spool types.
