Guarantees complete separation of the liquid from the sealing mechanism by creating an air gap at the top of the valve.

• The air gap, guaranteed even under extreme conditions, is achived by a conical body shape that maintains maximum distance between the liquid and the Sealing Mechanism; while obtaining minimum body length.

• Spring loaded joint between the stem and the upper float, to ensure that vibrations of the lower float will not unseal the automatic valve. Release of air will occur only after the accumulation of enough air.

• Funnel-shaped lower body ensures that the residue sewage matter will sink to the system and be carried away.

• Self cleaning mechanism.

Includes A.R.I patent: Rolling Seal Mechanism.

The valve may be flushed through a ball valve at the valve's lower part.
