What are the major components in a pneumatic valves

In a pneumatic valve, the valves control the switching and routing of air. The valves have to control the flow of compressed air and they need to control the flow of exhaust to the atmosphere. In a pneumatic switching circuit two types of valves are used they are 2/3 valve and 2/5 valves. The air cylinder comes in a variety of sizes and shapes. The major function of a cylinder is to convert the energy in the compressed air into straight motion.

What are the types of pneumatic actuators and where are pneumatic actuators used? What is the purpose of the actuator
A pneumatic actuator converts energy into motion. There are certain types of pneumatic actuators they are rotary actuators, pneumatic cylinder, grippers, rodless actuators, vacuum generators. These actuators are used for automatic valve operation. This actuator converts the air signal into valve stem motion and it is done by the help of air pressure that acts on the diaphragm or by the piston which is connected to the stem. These actuators are used to throttle valves for the quick opening and closing. The actuator is reverse acting if the air pressure opens the valve and the valve is closed by spring action. If the air pressure closes the valve and spring action opens the valve then it is direct-acting.

How is a solenoid valve is different from a pneumatic valve
The operation of the solenoid valve is entirely dependent upon electricity but the pneumatic valve operates with the help of electromagnetic force. Compressed air is also used for the movement of the parts.

What is a 3-way pneumatic valve
Mostly three-way valves are similar to two-way valves and the difference is that an extra port is used to for exhausting downstream air. These valves are able to control single acting or spring return cylinders and any load that must be pressurized and alternately exhausted

What is an electro-pneumatic valve
Electro-pneumatic valves are used for simple on-off function, in this valve we can control the pressure by manually opening a valve, automatically by detecting its pressure or by sending an electrical signal.
