SPRL V9-3-P duplex valve with ceramic disc valves for feed and return.
It is tapped 1/4″nps feed and return and will take standard npt fittings and our -6 banjos.
V9-3-P can carry the small selector plate 54mm in diameter or the standard plate @70mm interchangeable with other valves and other types.
V9-3-P is perfect for any low pressure return system.
The SPRL Valves, as designed, have a very nice 'feel' and are logical in use, however, there is a requirement in FAR 23 whereby the fuel valve must be turned from OFF to an ON selection simply by turning it, i.e. it should not have to be lifted up, pushed down etc, and it should also not be possible to turn it from an ON position to OFF without a dent.
