BUILT FOR SUPERIOR PERFORMANCE • Rated standard operating pressure 300 PSI. • Laboratory tested to 750 PSI. Engineered safety factor of 5X with respect to tensile strength. • Cast aluminum (per ASTM B-26) meets strength requirements of AWWA C512 standard while dramatically improving corrosion resistance. • Continuous acting mechanism seals at pressures as low as 2 PSI, providing the best published performance in the industry. • Lighter weight material aids in installation and mounting. IMPORTANT BENEFITS • Protects pipelines and pumps from air lock and vacuum collapse. • Eliminates air and prevents vacuum potential in pipelines. • Prevents reduction/impedance of flow due to air obstruction. Reduces head losses from air. • Reduces frequency of water hammer and vacuum damage. • High pressure rating allows use in hilly terrain with high heads or with high pressure pumps. • Large venting orifice rapidly exhausts or admits air during pipeline filling or draining. MATERIALS AND SPECIFICATIONS • Body and base are high-strength, corrosion-resistant aluminum. • A unique hard-anodized aluminum poppet and specially-designed cylindrical float provide reliable and consistent operation. • The guide rod and assembly hardware are stainless steel. • Pressure rating from 2 - 300 PSI. • Temperature rating 180 degrees F.

CONTINUOUS ACTING HIGH PRESSURE AIR VENT & VACUUM RELIEF = COMBINATION = AIR + VACUUM = AIR RELEASE Combination at all peaks. Also install at pump discharge. Air release on long horizontal runs. WATER SOURCE APPLICATION Typical installations include high points in pipelines for air release and at anticipated pipeline vacuum occurrence locations. They are also often installed upstream of check valves in pump discharges to vent air during start-up and to allow air re-entry when the pump stops. OPERATION Air Release Mode: When line is filled or pump started, air is exhausted through the valve....
