In the ISO number system, what number is used to indicate the pressure port or supply port?

How many switching positions are there in this valve?

It is a device that generates linear or rotational motions with the compressed air.

It is a device that controls the start, stop and direction of air flow.

It can convert the mechanical energy from motors and engines into the potential energy in compressed air.

It can remove impurities from compressed air before it is fed to the pneumatic components.

It uses the compressed air to generate one way motion, and uses a built-in spring or an external force to generate other

way motion.

In a double acting cylinder, air pressure is applied alternately to the relative surface of the piston, producing a propelling force and a retracting force.

The symbols on a control circuit diagram only show the functions of a valve, not the design principle and structure.

In a DCV symbol, the number of squares shows the number of ports.

Based on the figure, choose the best answer about the DCV.
