Nylon Reinforcement Diaphragm Anti Water Hammer Surge anticipating Valve
A2A5 is a surge anticipation valve and it can protect the pumps, pumping equipment and all applicable pipelines from dangerous pressure surges caused by sudden changes of flow velocity within a pipeline. When pump starts and stops gradually, harmful surges do not happen. Should a power failure take place, however the abrupt stopping of the pump can cause dangerous surges in the system
which could result in severe equipment damage.
Power failure for a pump will usually result in a down surge in pressure, followed by an up surge in pressure. The surge control valve opens on the initial low pressure wave, diverting the returning high pressure wave from the system. In fact, the valve has anticipated the returning high pressure wave and is open to dissipate the damage causing surge. The valve will then close slowly without generating any further pressure surges.
Service Fields:
For water system, irrigation system.
