Newton V9-4P Four Way Duplex Valve

Add to Wishlist
Part# 05-21697
MFR Model# V9-4


SPRL V9-4-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.

V9-4-P can carry the small selector plate 54mm in diameter or the standard plate @70mm interchangeable with other valves and other types.

V9-4-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.

Appears to be a very well built valve. Haven’t run it yet but it feels smooth and will work well with my EFII system.

The V9 and V10 are designed to fit in a narrow space with in line lines using AN-6 nipples part 05- 06926. For supply from the sides or underneath we suggest a banjo fitting, 05- 06474 as there is not room for two elbows.

Two inlet holes are designed with too short distance. The shape of the fittings are very limited. This valve is not so practical as as the price.
