Aspria Vacuum SystemsCVS-IAirflow Relief ValveCentral Vacuum > Installation & Fittings > Install Supplieshttp://www.aspria.systems/products/central-vacuum-airflow-suction-relief-valveAn Airflow Relief Valve is installed in a central vacuum system as near as possible to the power unit and provides an alternate pathway for airflow should the primary path become blocked. Often called a suction relief valve or motor protection valve and sold in a number of colors, this airflow regulation device uses an adjustable spring tensioned opening to allow airflow in to the vacuum system when it can not be pulled from the normal tubing system due to a blockage or clog. In the event an item was inadvertently vacuumed up that was so large or oddly shaped that it causes a clog in the vacuum line the airflow relief valve lets airflow in to "prevent motor damage".
