Pneumatic Valves

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 as safety valves, shutting off the fluid flow in dangerous situations or depressurising the system.

Types of Pneumatic Valves

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.

What are Pneumatic Valve 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 valve 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.
