Float Valve Extractors A79-001 Float Vent Valve Extractor Assembly The A79-001 Assembly consists of the extractor fitting body, extractor cage, and the A75-002 float vent valve. The extractor fitting mounts on the under- ground tank flange and secures and positrons the float vent valve in the tank. A 2" port on the fitting accommodates the tank vent line. The float vent valve can be removed from the tank, using the A560-002 extractor wrench, without the need for excavation. Overfill protection is provided as the float vent valve is designed to close at approximately 95% of tank capacity. As the valve closes, product flow rate from the delivery vehicle is dampened to prevent sudden line shock. When the valve is fully closed, flow rate is reduced by 99%. In the event of overfill, a standard '/a" bleed hole provides pressure relief for compressed air in the tank. The A79-001 Assembly is recom- mended for use in conjunction with Dual Point Vapor Recovery systems, and where underground vent piping of similar products may be manifolded. In these applications the float vent valve will reduce product crossover, (See also A75). Features a heavy-duty cast iron body, galvanized for rust protection.
