Air Cushion Valves

An air cushion valve is a critical component of a pipeline system designed to protect against the damage that can occur due to column separation when a pump is abruptly shut down. This phenomenon creates a vacuum within the pipeline, which can lead to catastrophic failure, including collapse or damage to the pipeline.

The air cushion valve helps prevent this damage by introducing a significant volume of air into the pipeline, thereby creating a cushion that can absorb the pressure changes caused by column separation. This action serves to break the vacuum at the separation point and reduce the inertia of the returning water column, thus ensuring pipeline integrity.
