This valve serves to regulate or control the direction of hydraulic fluid that will work moving the actuator. In other words, this valve serves to control the direction of movement of the actuator. Directional valves are named based on:
- Number of holes / working channel (port)
- Number of working positions
- Driving type valve
- Other additional names according to the characteristics of the valve.
Here are examples of the steering valve and its name:
