Pneumatic Valves: How Do They Work?

DAS Services Inc.

Pneumatic valves contain an array of pneumatic components. Pneumatic valves control the amount of air, pressure and rate when it passes through the pneumatic system. A wide range of industrial applications uses pneumatic valves. You have various pneumatic valves to select from. It is your responsibility to choose the best and suitable pneumatic valves for your industrial applications. Most industrial applications use functional directional control valves. 

How Do Pneumatic Valves Work?

The pneumatic valves are used to power the solenoid valve. Operating the pneumatic valves is easy. The basic components of pneumatic system are lubricator, compressor, air tank, valves and filter regulator. The pneumatic valve uses compressed air to transfer and take full control of the energy. The compressed air, which is acquired from the atmosphere, will be stored in the pressure tank. You can address different types of pneumatic valves and the operating mechanism of each valve will vary according to its type. 

Types of Pneumatic Valves 

  • Spring Offset Valve

The air-flow direction can be switched in this valve. A two-way directional pneumatic valve that operates in this manner is called a spring offset valve. The actuator will release the valve spool. The actuator itself will return the valve to its earlier position. 

  • Two-Way Directional Pneumatic Valve

This valve contains 2 ports and the air-flow happens in both the ports. The ports of the valve can be closed or opened. If the ports are opened, the air flows through the ports in the opposite direction to each other. If the ports are closed, then air would not flow through the ports. 

  • Three-Way Directional Pneumatic Valve

This valve contains three ports totally. All three ports will be connected to different components of the valve. The first and second ports are connected to the actuator and air-flow pipe. The third port can be used as an outlet. Any of the two ports should remain open and one port should be closed. If the first and third ports are open, then the second port should be closed. 

  • Four-Way Directional Pneumatic Valve

This valve contains 4 ports. Among the 4 ports, one port performs as an outlet, two ports are connected to actuators and one port is connected to pressurized air-flow. An additional port can be added to the valve if needed. If an additional port is added, then it can be used as a secondary outlet.

Why Pneumatic Valves?

  • Miniature size is perfect for limited space applications
  • These valves are highly useful tools
  • The versatility of the valves can be increased with numerous configurations
  • The valves can produce compressed air
  • The valves deliver convenient plumbing experience with a variety of porting options
  • The cost of the valve is low
  • The valves are durable
  • The valves are plated for corrosion resistance 
  • The valves are stronger and safe to use
  • Contains colored actuators for easy identification 

Therefore, we have discussed the types and working of the pneumatic valves. I hope that all those points would have conveyed useful information about the working of pneumatic valves
