INGESOA® Flapper Gates are specially designed air locks used to introduce abrasive or lumpy materials into possitive pressure or vacuum process systems.

These units basically consist of two doors or gates that alternately open and close to permit the passage of the material from the supply point into the process line.

The operating pressure differential is up to 1 bar gauge (15 psig).

These gates are motor driven or work under gravity. Pneumatic or hydraulic operated on demand. INGESOA® supplies custom configurations to meet a variety of application needs.

These range from high temperature and high abrasion, to very large gates for high capacity and severe duty.
