ANDAIR FS25 Series 1/2"...
Manufactured to the highest standards, 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. Duplex fuel selectors are also offered (see separate product presentations). FS16, FS20 and FS25 series of fuel selectors are designed for safety, provide a precise and smooth feel in operation and come in different types, ranging from Type 1 ON/OFF shut off valves to valves with multiple positions. To prevent the pilot switching the wrong tank or turning the fuel off 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.
