2” to 4” Industrial Continuous Acting Air and Vacuum Breaker guarantees complete separation of the sealing mechanism by creating an air gap at the top of the valve. The air gap is achieved by the air vents conical shape, which maintains the maximum distance between the liquid and the sealing mechanism, ensuring the residue waste will sink to the system and be carried away . Accommodates working pressures up to 150 psi. Available in reinforced nylon and stainless steel in 2”, 3” and 4” sizes.

| Product Advantages |
- 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 achieved by a conical body
shape that maintains maximum distance between the liquid and the Sealing Mechanism;
with minimum body length.
- Spring loaded joint between the stern 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 patent: Rolling Seal Mechanism.
- Reliable operation reduces water hammer incidents.
- Dynamic design allows high velocity air discharge, exceeding 12 psi differential pressure;
preventing premature closing.
