Nylon Reinforcement Diaphragm Surge anticipating Valve Stainless Steel Pilots
Description:
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 cutoff of a pump or rapid
closure of 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. Under normal conditions 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.
