Content DescriptionDual check valve type backflow preventers (for carbonated beverage dispensers, post mix type, and non?carbonated beverage dispensers) prevent carbon dioxide gas and carbonated water from backflowing into the potable water system which supplies the carbonating unit. These devices operate under continuous or intermittent pressure conditions. These devices consist of 2 independently acting check valves internally force loaded to a normally closed position and designed to operate under intermittent or continuous pressure conditions.About ASSEASSE, the American Society of Sanitary Engineering, is a nonprofit organization that develops and publishes standards aimed at preventing unsanitary design in plumbing systems. Headquartered in Westlake, United States, ASSE standards contribute heavily to the IAPMO Uniform Plumbing Code, the overarching standard for plumbing in the United States. With 70 member companies and many more individual members, ASSE work promotes the prevention rather than cure philosophy. |
