Venting and breathe valve Va
DN 10 to DN 80
Function
VA venting and breathe valves are primarily used where containers and pipelines must be ventilated. The float in the VA opens the valve when the liquid level drops. When the liquid level rises, the float is raised and is pressed against a seal. The valve is closed.
For perfect functioning, it is important for the venting and breathe valve VA to be installed vertically with the arrow pointing “up”.
