APCO Air Release Valves

Air Release Valves function to release air pockets that collect at each high point of a pressured pipeline.  Air Release Valves can open against internal pressure, because the internal lever mechanism multiplies the float force to be greater than the internal pressure.  This greater force opens the orifice whenever air pockets collect in the valve.  Air Release Valves are essential for pipeline efficiency and water hammer protection.  Email us for more information

APCO Air/Vacuum Valves

Air/vacuum valves are float operated, having a large discharge orifice, equal in size to the valves inlet.  Air/vacuum valves allow large volumes of air to be exhausted from or admitted into a water pipeline as it is being filled or drained.  As the pipeline fills, water enters the air valve, raises the float and shuts-off.  When draining the pipeline, the float drops, allowing air to enter, preventing vacuum, possible pipeline collapse or damaging water column separation.  Air & Vacuum valves are an efficient means to fill and drain pipelines.  Email us for more information
