Now we shall see some important air control valves in the following sections.

PNEUMATIC (OR AIR CONTROL) VALVES

1. Functions of Pneumatic Valves

The main functions of pneumatic valves are :

(i) To start and stop pneumatic energy;

(ii) To control the directional flow of compressed air;

(iii) To control the flow rate of the compressed air; and

(iv) To control the pressure rating of the compressed air.

2. Types of Pneumatic Valves

The pneumatic valves can be classified in many ways.

I. Classification based on their main function :

1. Directional control valves,

2. Non-return valves,

3. Pressure control valves, and

4. Flow control valves.

II. Classification based on their construction :

1. Poppet (or seat) type valves,

2. Sliding spool type valves, and

3. Rotary spool type valves.

Now we shall see some important air control valves in the following sections.
