Cast Iron Air Eliminators

The valve and seat assembly inside the air eliminator is connected to a stainless steel float. When there is no liquid in the body of the air eliminator, the float will be in the down position, allowing air or other gases in the vessel or piping system to escape. When liquid enters the body, it will lift the float and the valve will be closed off before any liquid can escape.
  • Rugged Cast Iron housing
  • Simple design for easy maintenance
  • Stainless steel internals
  • Optional Viton Valve Head for high temperatures and tight shut-off
