ANDAIR FS20-20-D2 Series...
The Andair standard fuel selector range incorporates 1/4"(FS16), 3/8"(FS20) and the 1/2"(FS25) valves. These valves allow for multiple tank switching of one fuel line (see separate product presentations).
Andair Duplex fuel selectors have two separate compartments so that two independent fuel lines can be switched simultaneously making them ideal for fuel injected or diesel engines where there needs to be a return line. It allows to pipe surplus fuel to the same tank from which it was drawn. This avoids overfilling the return tank or having an overly complicated fuel system.
Manufactured to the highest standards, all Andair valves are designed for safety, provide a precise and smooth feel in operation and can be supplied with custom engraving. They feature a large red lever with 'Fuel' engraved on it and a clearly labelled fascia plate to indicate which tank has been selected. It allows for a good solid detent at each tank position and also the button on top of the lever must be raised to switch the fuel off. All these features help prevent the pilot switching the wrong tank or turning the fuel off.
FS20-20-D2 fuel selectors has two 3/8" sections for feed & return and can be supplied with either male or female fittings (Thread: 9/16-18" Male AN-6 or 1/4" Female NPT) to meet application requirements. Engines that can benefit from this valve are Surburu, Continental, Rotax, and Diesel engines.
