Pneumatic Control 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?

Electric pneumatic air valves are the components responsible for regulating the rate, pressure, and amount of compressed air as it passes through a pneumatic system.

Pneumatic air valves perform a guiding and dosing function via regulating and locking elements. They’re controlled by special mechanical, pneumatic, or electromagnetic signals.

Pneumatic valves can perform all kinds of  tasks in varied complexities. They can be customized according to the specific application. Each type of valve is characterized by the possible mechanism positions and the number of ports or flow lines.

Which industries use pneumatic valves?

Air control valves are typically constructed from high-quality materials such as aluminum, stainless steel, and carbon steel. They are widely used in all types of manufacturing as well as packaging, automotive assembly, food and beverage processes and more.

Many industrial and manufacturing processes involve the movement precision and flow direction of hazardous fluids and chemicals. Strong and powerful systems that can operate under heavy payloads are required to achieve this. Pneumatic valves help these systems maintain precise movements even in intricate pipe networks.

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.

Pneumatic and other systems in your manufacturing operations can be complex and overwhelming. The JHFoster team can be your partner in choosing the right components, in the right systems, for the right applications every time.
