Unlike conventional relief valves, which open only when a high pressure wave hits, surge anticipation valves sense the precursor of the high pressure wave (pump power failure or low pressure wave) and opens in anticipation of the returning high pressure wave that follows. By opening, the valve prevents the buildup of pressure before it occurs.
Electrical power connection to pumping system for opening on loss of power or on a pressure switch low-pressure signal.
Valve closes after (adjustable) predetermined time on power failure or low- pressure opening.
Hydraulic, pilot operated, high-pressure relief opening.
