Tips to select the right pneumatic valve for your system

The market is filled up of different kinds of valves. Each of the valves is designed for a particular type of system and application. The pneumatic valve is a fairly common type of valve. Pneumatic valves consist of directional control valve. However, there are certain ways in which a pneumatic valve should be fitted. It should be done by some professionals.

Before that, you should know that there are further different types of pneumatic valves. Each type of pneumatic valve is based on different functions, performance and specifications. We have discussed some of the tips you should consider so that you choose the right pneumatic valve for your system.

Identifying Basic Functionality

Pneumatic valves come in a different number of ports. These are generally 2, 3, 4 or 5 ports. You need to choose the ports depending on your requirement. These ports generally have 2 or 3 valve positions. There is a unique directional flow path which is offered by each position.

Another important thing is the functionality which the directional control possesses. In case of 4 or 5 positions pneumatic valve, compressed valve flows out through one cylinder while the exhaust flows from the cylinder port. In the case of 3 position valve, the functions are normally closed or normally opened.

Identifying Performance and Specifications of operations

You will need to need to know the response time. You have to decide the speed at which the valve will shift. The valves could either be pilot operated or direct action. In case of pilot operated valves, the path for pilot air is opened or closed using the solenoid. These type of valves are cheaper to buy and it is less power consuming. Its response time is also slower and it is more susceptible to air variations. On the other hand, direct acting valves shift the entire valve spool using a solenoid. It is also more expensive and is more power consuming. However, the response time is faster and is not susceptible to any variations of air.

You should also consider the flow and power required for your valve. Based on the power, the connection requirement can be determined. The most common voltage selected for pneumatic valves is 24V DC. The connections can be connected using DIN connectors or hand wiring.


Choosing the correct pneumatic valve is important or else it might be problematic for the system.
