Principle
The valve adopts a unique spiral-type filter to collect air mass and micro air bubbles in the medium through the spiral groove of the filter core. Large air bubbles rise to the gas collecting chamber in the upper part of the separator. When the system is in normal operation, they are discharged through the air release valve at the top. 
Installation and Commissioning
Installation and Commissioning
