Surge anticipation valve for high to very high flow rates

The surge anticipation valve SAV 820E is designed for installation in a bypass line, prevents harmful pressure surges that can develop in pumping systems during sudden pump stoppage.

Unlike conventional pressure relief valves that open only when a high-pressure surge is encountered, the SAV820E already senses the preliminary stage of the high-pressure surge (pump failure or low-pressure surge) and opens in anticipation of the subsequently returning high-pressure surge. By pre-opening, the SAV820E inhibits the pressure rise before it occurs.
