The FS20x3 Fuel Selector is the most popular valve of the series. It has a 180 degree action between the LEFT and RIGHT tank. This makes it ideal for positioniong in the center of the aeroplane so that the handle 'points' to the selected tank. The red safety button must be raised to switch the fuel off.

On the FS20x3 there are 3 ports. The lower port is an AN-6 Male fitting. This is the outlet and it is machined to the base of the valve. The inlet ports can be any of the 3/8" fittings that Andair supplies and are at the 9 O'clock and 12 O'clock positions. At the 3 O'clock position there is a blanking plate that covers up a PTFE gland that opposises the forces of the other PTFE glands.

As all of the valves, there is a nice solid detent in each selected tank position and a clearly labled facia plate. To avoid incorrect fitting this plate can only be fitted on in one way with respect to the valve body.

This valve has found to be popular in the RV's and other aircraft where two wing tanks are required to be switched frequently so that balance is maintained. As the action is very smooth, it easy and pleasurable to change the fuel over.
