What are Pneumatic Valves?

A pneumatic valve (also known as a directional control valve) is a device that directs or prevents the flow of a fluid (either water or compressed air) within a pneumatic system.

What is the Purpose of a Pneumatic Valve?

A pneumatic valve plays an important role in determining how much air passes through a system and in which direction. This means they can be used as both control valves and safety valves, shutting off the fluid flow in dangerous situations or depressurising the system.

What are Pneumatic Symbols?

A pneumatic valve symbol is a graphical representation of this device in a pneumatic system schematic. These symbols help engineers and technicians identify and understand the valves involved during maintenance and troubleshooting, ensuring that the pneumatic circuit meets the precise operational requirements.

Additionally, pneumatic diagram symbols simplify the process of designing pneumatic systems by offering a standardised visual language that is easily recognisable by engineers in multiple countries. This allows for easier communication between different groups of workers and makes the assembly process faster and more accurate to the required specifications.

Pneumatic Valve Types and Symbols

Here are some common types of pneumatic valves:

  • Solenoid valve: This valve responds to electric signals by opening and closing. They are commonly used in manufacturing environments.
  • Check valve: A one-way valve designed to prevent backflow in a system, preventing damage and water hammer.
  • Air-operated valve: This valve responds to air pressure by applying force to a piston or diaphragm. As such, they are found in environments that require a high output but do not rely on electricity.
  • Mechanical valve: This type is operated by hand. Thus, it is often used in situations where electricity would be hazardous or impractical for the tasks at hand.

Add Pneumatic Valve Symbols Easily With Capital X Panel Designer!

Pneumatic valve symbols are extremely complex, making them difficult and time-consuming to manually draw. Capital X Panel Designer lets you skip this process entirely. All you have to do is browse our selection of pre-made symbols and then drag and drop them into your schematic. With this easy-to-use electrical CAD software, you will enjoy a huge boost to your workflow productivity.
