Designed to discharge volumes of air during the filling, admit air into the system during system drainage, and release volumes of air when the line is under pressure.

Why is air a problem in a system?

Air in a system impedes the flow of energy transfer. Hence, it is important to release the air to avoid unnecessary headloss and flow restrictions. Air pockets do also lead to water hammers that can damage equipment including other valves in the pipeline.

They are suitable for various fluids, though please consider the material of construction for the selected valve to ensure that it is suitable for the related application.

FIVC Air Vents are available in a variety of specifications, including single-, double or triple-action vents with different pressure ratings, threading, flanges, materials, etc.
