AVI offers a variety of drain valves for tank draining and sampling requirements. The ability to drain and pull samples from aircraft fuel systems is an important part of the fuel systems design. AVI has been designing sampling and drain valves for nearly 60 years.
Many of the early valve designs were so well engineered they are still in use today. Sampling drain valves are typically poppet style valves that allow for a small amount of fuel to be pulled from the tank during pre-flight safety inspections.
