Surge Anticipating

Abrupt pump stopping is followed by a pressure drop as the water column continues traveling along the line.

The returning column hits the closed pump check valve, creating a high pressure surge wave, which travels at up to 4 Mach.

Eliminating such surge requires anticipation and pre-action.

DVD Surge Anticipating Valves react to the pressure drop, accepting the returning column while already open, thus eliminating the surge.
