Nylon Reinforcement Diaphragm Surge Anticipating Valve Hydraulically Operated

Hydraulically operated Nylon Reinforcement Diaphragm Surge Anticipating Valve

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 stop 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.
