The manufacturer of this valve was surprised to be asked to produce a simple ON/OFF valve; ON/OFF valves are, after all, available very cheaply. This ON/OFF valve has the same highly desired qualities as other products they offer: a distinctive, positive snap feel and the highest quality possible.
There are two entries and one exit which is tapped 1/4 inch NPT for your engine feed. The entry pipes are linked so cross feed will occur in flight and when selected ‘OFF.’ see 'in the box' for the fittings supplied.
This is one of the nicest and well made parts I have gotten from AC Spruce.
Just a line re this review. (5 * - I am biased) We get no leak reports elsewhere my guess is that Alan is over tightening the assembly, or maybe is using too much sealant and that can push the seal out of place. Replacement seals would have been supplied on request.
I liked it a lot at first, nice billet construction. The weak point is the non-standard AN parts and O rings. Mine started leaking at 10 hours because of the O ring, I had a spare from the kit but when I replaced it, the sharp edges cut it also. Looking under accessories I don't see where i can buy the O rings so its junk.
Correct, the entry port is on the side inline with another port. The exit port would be the port on the bottom. This valve will come with a plug so you are able to block off the second entry port.
This unit is received in the box securely assembled although the instructions found inside the box indicates that the valve is loosely assembled.To take the unit apart, there is one screw located top/center that removes the switch and spring underneath. After that is removed, there are three additional screws that remove the plate from the valve firewall. There are two screws located at the bottom of the firewall that hold on the bottom cover. Instructions are included that explain how to take this unit apart.
No, per the supplier, that is not possible.
Per the manufacturer: We have not tested V2 to this pressure but I know it will carry at least 25 psi. We could test if needed. However I think that the valve is usually installed upstream of the pump so experiences 0 +/-- 2psi in service.
