Overview

SPRL V9-3 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 can carry the small selector plate 54mm in diameter or the standard plate @70mm interchangeable with other valves and other types.

V9-3 is perfect for any traditional return system but Rotax ask for over-pressure protection when the fuel is turned off and may be heated after shut down.

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.

Q&A

Q: I want to install an UL Power 520i. I have 1/2 aluminum fuel lines from my tank and need a 3 place Valve Left/Right/Off. What is the difference between the SPRL3 and SPRL4 Fuel selectors and which one gives the biggest flow to the engine?

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.

Q: Which exact fittings are included (if any), and if none are included, can you clarify precisely what the threading of each port is, so one can properly order the correct fitting?

The unit comes with 3 fittings for the fuel supply, which are male AN6 flared threads. The return ports are 1/4" NPT, which the builder will need to order separately.

Q: What is the difference between the SPRL V3 and SPRL V4 duplex valves?

Per the manufacturer: The V3 has 1/8"NPT threaded return lines, and the V4 has larger 1/4"NPT threaded lines.

Q: What is the thread size for the supply connections?

The thread for the supply side needs the AN6 banjo fittings.

Q: Is the SPRL V4-4-P a four way (left, right, both, off) that also controls and shuts off the return line?

Yes, this is correct.
