What is a pneumatic shuttle valve used for?

A pneumatic shuttle valve is designed specifically to control the flow of compressed air from one of two input lines to a single output. This function allows the system to select between different pressurized air sources based on availability or operational needs. By routing airflow from the active input line to the output, the shuttle valve plays a crucial role in ensuring that pneumatic systems can operate seamlessly and with the required air supply.

In practice, this means that if one air source becomes unavailable, the shuttle valve can automatically or manually select the other source to maintain operation without interruption. This ability to manage airflow effectively is essential in many applications, such as in automation and machinery where consistent and reliable air supply is necessary for proper functioning.
