No Slam Operation Surge Anticipating Valve For Protecting Pumps / Pumping Equipment

Surge anticipating Valve Anti Water Hammer Stainless Steel Pilots Nylon Reinforcement Diaphragm Ductile Iron ​

A2A5 is a surge anticipation valve and is for protecting pumps, pumping equipment and all applicable pipelines from dangerous pressure surges caused by rapid changes of flow velocity within a pipeline.
When pumping systems are started and stopped gradually, harmful surges do not occur. 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 to 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 effect, 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.
