I have installed several and am using the Kimball valve . I can not see how the
valve could close on itself. It is a rotating ball valve style. I have mounted
the control cable such that it sticks out in the way of my leg so it hits
me in the knee when pulled out to the closed position. The microswitch also
does not allow me to energize the start switch unless the control cable pushed
in all the way and at that time the bright yellow indicator light goes out that
is next to the start switch telling me the valve is open. And at that time
I should be looking at the oil pressure next during run up. I don't see how
the oil shutoff could close on it's own since it takes a fair amount of work
to move it in either direction even with the control . In my opinion the only
way to close is for me to pull it to the off position which is in my way to fly
and look at the glaring yellow light telling me the valve moved off the full
open position.

Hi Dale,
your system sounds quite reasonable. How do you activate the valve, by push-pull
wire like most of the cockpit levers do ? I suppose the yellow light switch
is triggered by the valve lever and not by the cable handle ? Id place the air
start coil switch there as well - respectively a two position switch: When the
yellow light is on the other contact is open -- when the light is out the other
contact closes for starting. So you effectively control the function of the
switch by looking at the lamp to go and off as well - the only way for checking
a malfunction.

Non locking push pull control (aircraft spruce) I uses two stops on both sides
of wire where it connects to arm on valve so it won't ever slip.
24 volt light wired to the starter button
Micro switch on Kimball shutoff ( supplied with valve )
Voltage must pass from one side of start button through micro-switch back to start
switch where it connects to start solenoid wire (Not to switch)
there is two connections on micro-switch so you can wire light to other connector
on so it is on when valve is off and on when valve is closed.
Micro-switch is activated on arm of valve not on wire or control wire and comes
already screwed to valve (don't over tighten screws on switch).

Dale;
I recently installed the Kimball valve on my CJ. The installation is
basically the same as yours with some minor differences. I used a two light
system taking advantage of the NO & NC features of the micro-switch and
installed a lockable cable assy. with an 0.072" wire.
Engine start power (for boost coil & air solenoid) is re-routed from the
Start Master CB/Switch to the Start button through the valve micro-switch.
With the valve arm in any position other than fully open the RED light is
illuminated from the NC contact. With the valve fully open power is
supplied (through the NO contact) to energize the start button and
illuminate the GREEN light.
In flight at any time the valve position can be confirmed by energizing the
Start Master.
The Press to Test circuit of the indicator lights is powered directly from
the 27VDC bus. so the lamps can be tested any time the Bat. Master is on.
There is no doubt that the position of the valve arm is the position of the
actual valve as may not be the case with an electrically driven valve.
I too have concerns with the control wire attachment to the valve arm. A
single set screw just does not meet any reasonable safety requirement. I
could not find suitable wire clamps as you did so I manufactured a new
stainless steel arm bushing with the 8-32NC thread extending over the full
length of the bushing. This allows a screw to be driven on top of the set
screw as a safety. Better than nothing?
Over a period of at least two weeks I tried to share this concern with
Kimball but they were simply not answering the phone!!
The Kimball valve is not a ball type. It is unique and probably their own
design and looks very good.
Valve operation is very smooth. Any binding after installation is a
function of the control installation which needs some careful planning. One
necessary item not well provided for in the valve design is the fact that
for smooth operation the cable housing clamp must be allowed to swivel a
small amount.
Cheers;
Walt

I do realize it is not a ball valve I stated ball style. Don't know the technical
name for what it actually is .I will call it a cylindrical rotating single
orifice super custom do-hickey dildo valve (Dildo for short to quote a Yak friend
of mine , some of you know of whom I speak)
I installed it pretty much straight forward of the way Kimball uses it on the Pitts
Model 12. been using it for years. works for me. Anyone can make something
more complex than it needs to be. I custom made the SS wire stops in my machine
shop. The best way to fix the issue is sell the plane.
Sooner or later everyone will pick this fix. No one way to do anything.

Now that looks very racy indeed ! I guess the valve is mounted on the oil tank
? In this forum I think to remember that there have been reports of fractures
of the oil tank joint as the valve assembly is a bit massive. Wouldnt it be safer
to place the valve somewhere on the fire wall with a hose connecting to the
tank? On the 18 T I put the actual ball valve on the right side next to the
oil "filter" .

As far as I know those reports referred to the motorized valve which is
considerably heavier. That does not relieve the concern though and I spent
much time trying to find a way to firewall mount it. The valve
configuration does not lend itself to firewall mounting on the CJ.
So it is tank mounted but it is also directly braced to the firewall
eliminating any possibility of relative motion between the valve and the
tank.
