What is the primary function of the pull away device in a CNG setup?

The primary function of the pull away device in a CNG setup is to enable quick disconnection in emergencies. This device is designed to automatically disconnect the transfer hose from the fueling system when a significant tension or force is applied, such as if a vehicle accidentally drives away while still connected to the fueling station. This feature is crucial for ensuring safety during CNG fueling operations, as it minimizes the risk of leaks and potential hazards that can arise from a connected hose being forcibly detached.

In CNG fueling systems, where high-pressure gas is involved, having a reliable means of disconnecting quickly is vital to prevent accidents and protect personnel and equipment. The pull away device thus plays a critical role in maintaining the safety of CNG operations by providing a fail-safe mechanism in case of unexpected events.
