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.

Update: during installation of the V9-3-P valve, I realized that the port spacing is too close to allow turning in 90-degree AN822-6D elbows. If straight nipples (or maybe 45 degree elbows) wont work, you must use the optional Newton AN6 banjo fittings (05-06474).
Very well made valve. Has a nice solid feel, and moves smoothly between settings (the knob sort of rocks up and down into a detent). 1/4 NPS threads in the body, but no fittings are included.

The flow rates are the same, but the SPRL3 has 3 positions, Left, right, & off. The SPRL4 has 4 positions left, right, off, and both.
All the threads are 1/4 NPS.
Per the manufacturer: The V3 has 1/8"NPT threaded return lines, and the V4 has larger 1/4"NPT threaded lines.
All the threads are 1/4 NPS and accept -6 nipples (05-06926) or a -6 banjo (05-06474).
Yes, this is correct.
