Danfoss AKVA 20 is an electrically operated expansion valve designed for use with refrigerants R717, HCFC, and HFC. It features a maximum working pressure of 42 bar g (609 psi g) and a maximum operating pressure differential of 18 bar g (261 psi g). The valve can be used in environments with ambient temperatures ranging from -40°C to 50°C (-40°F to 120°F) and media temperatures ranging from -40°C to 60°C (-40°F to 140°F). It is made of corrosion-resistant P285QH steel and requires qualified personnel and processes for installation.
