Reliable and precise is what characterizes a 3/2 valve. These valves are crucial for regulating air flow in various applications, including single-acting cylinders.

In this article we take a closer look at the specific workings of the valve and why they are so valuable. With expert advice and the wide range of 3/2 valves, you've come to the right place at Pneuparts.

What makes a 3/2 valve important?

A 3/2 valve is so named because this valve has three ports, supply (1), labor (2) and bleed (3) for the air connection and two switching positions. By introducing compressed air into the cylinder and then releasing it, it enables a new working stroke.

In pneumatic systems used in industries or automation technology, among others, these valves are an important component because of its precise control for the flow of air and fluids.

A properly chosen 3/2 valve allows for fast switching within your pneumatic system.

What makes a 3/2 valve ideal for use?

Compactness
Low maintenance
Long service life

3/2 normally open (NO)

3/2 normally closed (NC)

In practice, 3/2 valves are used for controlling single-acting cylinders, starting and stopping air flows and as control signals within pneumatic systems.

In one position, compressed air is added through port 1 and passed through to port 2 so that the air controls the cylinder. In the other position, port 2 is vented through port 3, releasing pressure and returning the cylinder to its starting position.

Ideal for situations where only one direction needs to be pressurized and others vented. Depending on the installation, 3/2 valves are available in various operating modes: electric, pneumatic or mechanical.

3/2 valve: this is how it works in practice

To connect the valve, you will need the following:

Compressed air source / compressor
3/2 valve
Suitable cylinder
Control device
Hoses
Couplings
Possibly a manifold block

In what applications do you encounter 3/2 valves?

The 3/2 valves are found in numerous applications in various industries, including:

Safety applications: used to control air pressure for emergency stop functions
Automation systems: to control air supply to various components, such as grippers and pistons
Pneumatic cylinder controls: to control the air pressure that makes pneumatic cylinders work

What should you consider when choosing the right valve?

When choosing the right 3/2 valve, there are several considerations to be made. First, you need to determine the maximum pressure and flow rate that the valve should be able to handle. Also take into account the application, making sure the valve is suitable for the conditions in which it will be used. In addition, you should also pay attention to the choice of materials and the ambient temperature.
