After a long development process, here's a completely new family of Fuel Valves. Hi-Tech Seals give easy operation and are suitable for all current fuels. The simplicity promises a long reliable life.
The SPRL-V1 is a three/four way fuel selector offering left-off-right and both if required. There are 90 degrees between selections and the absence of a lower fitting reduces the depth required. These English fuel valves have some great features that make them better than the rest. Ceramic disks have no soft moving/rubbing seals to wear out, unlike other valves but also give an 'indefinite' life with a very smooth light action. The lift and turn selector is instinctive, secure, and easier to use than the complex 'lift button' type. The locking detents avoid accidental movements. The fixings match most installations, and the internal ports prevent cross feeds, unless 'selected to 'Both'. Male AN fittings enable you to plumb straight into the aeroplane system with no extra fittings to buy. The lightweight alloy construction is anodized for protection; the Viton 0 ring seals are suitable for all current fuels. For experimental aircraft only. Fittings must be purchased separately. Please note that the accessories listed below are the the only compatible accessories; other standard accessories will not fit these valves. FAR 23 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. See V1/V3/V4 valves with a 'conforming' selector. |

It’s high quality and pretty economic
High quality Fuel Selector Valve with a low profile. Operation is smooth and quality of construction is excellent.
Did not use returned, because I ordered the wrong part. My mistake, misread the description. AS quickly provided return instructions and its on the way back to their warehouse.
High quality valve, has positive stops at each location. Easy to install
I selected the 4-way non-conforming SPRL valve on my personal customized Sportsman, N11YM with over over 300 hours use by 7/11/16. For you kit aircraft builders that want excellent quality with attractive pricing, I believe Robins valve is the best bang for the buck on the market.

Awesome piece of engineering! Operates very smoothly with a good positive selector lock at indent positions. The standard AN fittings saved a lot of money as compared to other fuel selectors and also allowed installation in very tight space without need for selector handle extension or other complicated modifications. Also received excellent and friendly support from manufacturer. Thank you!
The SPRL 3-way valve is a very well designed, smooth operating and robust fuel selector. It replaced the original weatherhead fuel valve in my RV4 that had become very difficult to operate, no matter what I tried to lubricate it with, or how many times I replaced the O-rings. The only negative for me had to do the installation in the confined area of the RV4 where the fuel selector pretty much has to go. The SPRL valve is compact, but only in the vertical dimension. If you have bulkheads, ribs, or other structural components around the valve, it can be a challenge to install. All three of my ports have to turn 90 degrees very close to the valve. I couldn’t orient it with the left tank at 9 o’clock, and the right tank at 3 o’clock, because the outlet was so close to a bulkhead. The weatherhead valve has its outlet coming out the bottom which makes installation positioning much more flexible. My left tank is at about 7:30, and right tank about 1:30, because that’s what had to be done in order for it to fit. It works fine, and is a high quality valve, but installation was challenging.
4 star so as not to distort the rating. I note Jeremies comment- failure to help was simply fear that a one off drive might be unsatisfactory and damage our reputation- we have seen some terrible drives made by even respectable aircraft manufacturers. Ours will work and costs about the same as the incorporated universal joint......
Decent Valve. I bought this to use with remote mounting of the valve. Unfortunately because the face plate shaft is the same shaft that is in the valve, it will only work remotely with the $100+ extension kit. I tried to get just the shaft yoke from the manufacturer, so I could build out my own drive line, but they would not accommodate.
Q&A
Yes, this is the correct description of the 4-way valve, part # 05-04451. Off, Left Only, Right Only, and Both.
These are shipped with the valve only. It does not include any fittings in the package. You will need to purchase fittings separately, 05-04452 (NEWTON SPRL FITTING AN6 MALE) and 05-04453 (NEWTON SPRL FITTING AN8 MALE).
Width of top is 2.75" (widest part), Depth is 2.4".
The difference between the two is a conforming selector will have an indentation when you turn the knob and a non-conforming selector will not have an indentation but instead you will have to lift the top selector to turn it to a different selection.
This does not have a both position. The SPRL V1-4P will have a both position.
That is correct, this will have a conforming selector that you will feel when you change positions. No special fitting is required to change its position.
Yes, the valve can be moved fronm left to right without going through off.
In the 12 o'clock position, feed would come from both tanks L & R.
No, these will not work in a fuel injected system.
When the V1 valve is in the off position there should be no crossflow between tanks.
