2/2 Solenoid normally open
The 2/2 solenoid normally open valve is a type of directional valve, the port direction change is achieved using energizing the solenoid coil, which pushes the plunger against the spring to open or close the port. Once the coil is de-energized by the spring return, it will return to its normal position.
The above diagram simply describes the features of the direction valve. The two square portion is a representation of the number of positions the valve is capable of. And the number of ports is counted in any one square portion, don’t count both squares. In this type 2 ports and 2 positions are available.
The spring attached portion always represents the normal condition (de-energized), here it is in the normally open state shown by the means of an arrow from the input to the output port. The solenoid attached box represents the energized condition, as you see the port is closed stopping the movement of the medium from either side to another side of the port. Hence combining all its features it was named so.
