Figure shown the electro-pneumatics circuit to be operated. And to be able to extend the piston rod of a cylinder , if only :-Figure shown the electro-pneumatics circuit to be operated. And to be able to extend the piston rod of a cylinder , if only :-

• Push button S1 is not pressed, the solenoid valve switches to the actuated position. The piston rod extend.

• Push button S2 is pressed, the solenoid valve remains in the normal position. The piston rod is retracted.

• At least one of the two push buttons is pressed, the solenoid valve switches to the actuated position. The piston rod advances.

• Both push buttons S1 and S2 must be pressed simultaneously, the solenoid valve switches to the actuated position. The piston rod advances.
