Description：The dirt separation principle of the ACOL Excoll Large AS3 series spiral collection valve device is similar to the microbubble separation principle: in order to reduce the flow rate, the water flow is guided to an area with a cross-section larger than the connection size. The pipeline network is bound to generate fluctuations, causing heavier substances to move in uncertain directions. Based on volumetric flow rate, density, and particle volume, some pollutants are guided to the bottom of the tank during their natural separation process. Extended valve body, specially designed for high flow systems.
