Today we will discuss:
Four Way Directional Valves in a Circuit
All valves have a body and an internal moving parts, the moving part of all valves has two positions – both extremes. These two positions are illustrated by two separate squares. Each square is viewed by means of arrows how the spool is connecting the passages within the body at that point and time.
When they are placed inside of a circuit, one square and only one square, is connected in the circuit. When it is like this, the state within the valve is shown while an actuator is moving in one direction. To have a clear picture of the actuator moving in the opposite direction, the other square of the symbol is mentally slid into the circuit.
A directional valve symbol allows only two spool form within a body is known as a two position valve.
If you need to leave a question, please do so. We would be glad to hear from you.
