This valve has been designed for an efficient discharge of air from small water network systems, filters, containers and other devices where trapped air may impair the systems operation.The valve is appropriate for:
- Expelling the air at high flow velocity during the initial filling of the system.
- Introducing air when the pipe drains, maintaining atmospheric pressures in the air when the pipe, preventing collapse and cavitation damage to the conduits.
- Surge arresting when the pipework has been drained.
