The Andair FS25-20-D2-6M is a duplex fuel selector valve for fuel-system layouts requiring simultaneous switching of separate feed and return lines. Its duplex arrangement uses separate internal compartments, allowing returned fuel to be routed back to the tank from which it was drawn.

This male-connection version combines a 1/2 in feed section with a 3/8 in return section. The selector provides LEFT, RIGHT and OFF positions; the OFF position requires the red button on the lever to be raised.

• Duplex fuel selector configuration for separate feed and return circuits
• 1/2 in feed section and 3/8 in return section
• Male AN-8 / JIC-8 feed connections and male AN-6 / JIC-6 return connections
• Polished ball valves with PTFE seals
