Reliable Pneumatic Valves

A lot of things can go wrong in pneumatic systems without the right components – there may be air seal leaks, damaged or dirty filters, or an excess of air choke. These issues can be time-consuming and costly. Choosing the most effective parts is more than just considering their applications.

One integral component that should not be overlooked are pneumatic valves. Not only do they control the direction of air flow in critical operations in the system, but they are also a possible source of issues, especially if they are not of good quality.

Issues with pneumatic valves can lead to more costly problems all over the system. By reading this, you are already taking the first step in avoiding this problem — because choosing the right pneumatic valve starts with choosing the right pneumatic valve manufacturer.

At JHFoster, we provide a wide range of reliable pneumatic valves for an array of applications.

What Is a Pneumatic Valve?

A pneumatic valve basically controls the flow of air, or any gas, in a pneumatic system.

These valves regulate the air from its source and redirects it to tubes, pipes, or other pathways wherever it is necessary. In some applications, pneumatic valves also control the amount of air flow and not only its direction.

What Are the Types of Pneumatic Valves?

There are several types of pneumatic valves, mostly depending on their application. They may be categorized according to the number of exit or entry points or according to the number of airflow paths. There are also electric or air-operated pneumatic valves. Here are a few examples of the possible classifications:

Two-, three-, or four-way directional valves – These pneumatic valves are classified based on the number of ports they have. Each port serves a unique purpose – whether it be intake, exhaust, or connected to an actuator.

Open or closed resting state valves – Valves with open and closed functions usually serve to better regulate airflow by restricting it. When these valves are closed, they will likely not allow any kind of airflow through them.

Valves that use spring offset mechanism – Some pneumatic control valves have a spring mechanism that is used to close or open ports. These springs often work to return the valve into its prior position.
