What does a check valve do?

This check valve serves as a critical safety component within the pneumatic brake system of heavy commercial vehicles. By allowing air to flow in only one direction, it prevents pressure loss from one circuit to another, ensuring that the vehicle can be brought to a safe stop even if a localized failure occurs. It is engineered with high-strength components to withstand rigorous heavy-duty service conditions.
