        A2A5 is a surge anticipation valve and adjusted to eliminate hazardous pressure surges typical of water hammer conditions. A water hammer is caused by a sudden shutoff of a pump or rapid closure of a main valve, causing a fast propagation of low-pressure front, followed by an extremely high-pressure back-wave. A series of pressure waves, each one composed of alternating low and high pressure is created within a few seconds. A2A5 is a piloted hydraulic valve activated by line pressure. The valve has two pilots, for high and low pressure. Normally the A2A5 is closed. It opens when the line pressure drops below a preset pressure, in anticipation to the following surge, and remains open until the fluctuations
    subside.
