    D-060-C HF, D-062 HF | Combination Air Valve

    285 PSI , 360 PSI – 1"-10"

     

    Description

     

    The D-060-C HF, D-062 HF series Combination Air Valve has the features of both an air release valve and an air & vacuum valve. The air release component is designed to automatically release small pockets of air to the atmosphere as they accumulate along a pipeline or piping system when it is full and operating under pressure. The air & vacuum component is designed to automatically discharge or admit large volumes of air during the filling or draining of a pipeline or piping system. This valve will open to relieve negative pressures whenever water column separation occurs.
