The FS20-3 is the most popular valve that Andair produce. It is a three way selector with the positions LEFT - RIGHT - OFF. There is a 180 degree action between the left and right, giving it a logical arrangement. Generally this valve is used in low wing aircraft with a tank in each wing, and has been popular with the RV range of aircraft. Andair's test plane - RV6 has a FS20x3 installed. The valve has a beautifully smooth action between tanks which is an important feature when one is normally switching tanks every 20 minutes or so. Also there is a strong, firm detent at each tank position giving a welcome reasuranse that the valve is in the correct position. With the valve comes a clearly labled fascia plate.
On the FS20x3 there are 3 ports. The lower port is the outlet to the engine and can be Male AN-6, Female 1/4NPT or a Banjo fitting which is a 360degree adjustable fitting with a male AN-6 end. This can be configured whilst ordering.
The inlet, side ports can be any of the 3/8" fittings that Andair supplies and are at the 9 O'clock and 12 O'clock positions when looking at the valve with the brass ball spindle pointing upwards (see exploded image to left). At the 3 O'clock position there is a blanking plate that covers up a PTFE gland that opposises the forces of the other 2 PTFE glands. This cannot be removed.
One of the great features of this unit is that when the selector is in the OFF position, there is no cross feed between each tank. So if you have your aeroplane parked on a slope, or if one tank is fuller than the other, no crossfeed will occur.
