Abstract:
A valve is provided having an air gap to protect against backflow in a fluid system. The valve can also be used to control fluid flow while providing such backflow protection. The valve can be used with e.g., a reverse osmosis water filtration system and/or other systems. By incorporating both backflow protection and flow control into the same device, efficiencies in space, complexity, and/or installation time are provided.
