The Pump Air Valve, typically referring to the core pneumatic reversing mechanism in Air-Operated Double Diaphragm (AODD) pumps, is responsible for alternately feeding compressed air into the left and right chambers of the pump to drive the diaphragms in a reciprocating motion for fluid transfer. It achieves automatic reversing through mechanical or electromagnetic means to ensure continuous pump operation. Common designs include spring-assisted and centerless configurations, which guarantee durability and reliability in industrial environments.
