What are Pneumatic Valves?

Pneumatic valves are components that are essential to control the amount of air flow and pressure across a pneumatic circuit. Pneumatic systems can be used to monitor and modulate the flow of air in industrial systems. In other applications, the air controls liquid media like water or oil inside the system. You can find these pneumatic systems in industrial applications like diesel engines, train doors, mechanical clamps, and automatic production lines.

When a pneumatic valve is used to control pressurized airflow, it does that at the source, thus regulating the rate of the air passage in a pneumatic circuit. You can choose to manually open and close the valve or use solenoids or motorized actuators to switch on the valve electronically.

When air is used to control oil, water, or any other fluid, the pneumatic valve controls the airflow throughout the system. The valves referred to in this scenario are known as pneumatically actuated valves.

Pneumatic valve parts come in different varieties depending on the:

  • Number of air entry and exit ports
  • Available switching positions
  • Position of the valve in an un-actuate state
  • The mechanism used to open or close the valve
