Nylon Reinforcement Hydraulically Operated Surge Anticipating Valve IP68
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.
Features:
• No slam operation
