Air inlet check valve
Protection of Pipelines Against Vacuum in Drinking Water Networks
The Role of the Air Inlet Device in Protecting Water Supply and Distribution Pipelines:
Protection of Pipelines Against Vacuum
The air inlet valve allows the admission of a large volume of air into a pipeline during an accidental vacuum or during a drainage operation.
This device protects pipelines by preventing their damage, as well as the suction or deterioration of joints. It thus ensures the preservation of the hydraulic network's integrity.
It plays a crucial role in avoiding damage caused by vacuum conditions, particularly during the closure of a valve or a sudden interruption of flow.
The air inlet check valve allows air to pass through the duct at a high flow rate during accidental vacuuming or draining.
It prevents damage to the pipes and/or the suction of the seals.
