Surge Anticipating Valve
Ductile Iron Surge Anticipating Valve Anti Water Hammer Available Nylon Reinforcement
Ductile Iron Surge Anticipating Valve Anti Water Hammer Available Nylon Reinforcement A2A5 is a surge anticipation valve and adjusted to eliminate hazardous pressure surges typical of water hammer conditions. A water hammer is caused by an abrupt shutoff of a pump or rapid closure of a 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
Hydraulically Operated Surge Anticipating Control Valve With Diaphragm Actuated
Dsecription: A2A5 is a surge anticipation valve and is hydraulically operated, diaphragm actuated valve. The valve senses line pressure, opens in response to the pressure drop associated with abrupt pump stoppage. The pre-opened valve dissipates the returning high pressure wave, eliminating the surge. The A2A5 smoothly closes drip tight as quickly as the relief feature allows, while preventing
