WTB: Brittain solenoid valve 4085-2C

[Igor_U]

As a title says, I am looking for the Brittain solenoid valve 4085-2C. Clarence recently sold one so maybe someone else has one is stock.

I have a set of modern control wheels with shaft that can be installed in classic Mooney and with the solenoid, I could install them in my 67 F.

Please PM if you have one otherwise might have to sell the control wheels.

Igor,

catch up with @sdflysurf...

I think you may be on the same team...

I bought this 12v solenoid:

https://www.amazon.com/dp/B084YTNG2P/ref=cm_sw_em_r_mt_dp_WMZEGKJNMZ2GV862G2CJ?_encoding=UTF8&psc=1

And these connectors (2 in the pack of 1/4" NPT to 1/4" hose barbs):

https://www.amazon.com/dp/B07NB6VZF7/ref=cm_sw_em_r_mt_dp_N8SWVVKG4R9V2X6WJ046?_encoding=UTF8&psc=1I

I just received them today and I am going to wire it up to a switch for "wing leveler on" and "wing leveler off" - I'll check it out and report back - but the connectors fit nicely with the 1/4" inside diameter vacuum line I have.

(And now I can use a PTT button built into my yoke!)

I bought something similar and tested it; it works but my IA wouldn't be comfortable signing it as it's not approved part.

I think this is a very controversial subject - but when I was looking for this fix I could not find a GOOD used replacement of the same part, nor could I find a NEW TSO part that was meant for this, so according to the A&P it will be a signoff for 14 CFR 21.93 Minor alteration.

Talk with your A&P.  Maybe you can convince him that when dealing with 1960s planes there needs to be some flexibility!

Someone else can chime in since I am not the expert - but in all of my reading regarding part 91 operator minor alterations - I didn't need my IA to sign off - just an A&P logbook entry.

wow isn't this the definition of owner produced part ?  Wonder if i could use one to enable/disable the wing leveler thru a switch instead of the yoke button

Not really, An owner produced part would be building a Brittain valve from scratch as close to the original design as possible.

I'm interested. PM sent.

Did you find what you were looking for? If not, I'll look...I'm pretty sure I've got one.

Brittain parts are always being sought... 

So... if you have any... bring them out.

Hi 

Thinking again about it, if I were you and if I couldn't find the original brittain valve, then instead of plumbing and wiring a solenoid that comes with updating your breaker drawing and maybe upping your breaker, all the heat issues etc etc, I would double up the already existing pneumatic bypass valve that's on the yoke with something like this:

Dude,

That opens a bunch of interesting ideas...

People like the panel mounted switches a bit more than the yoke mounted ones...

Mostly because the PTT switch that inhabits the same hole, has priority...

Panel mounting a modern vac switch could make a great alternative...

Of course... great ideas need to be approved for install by somebody like your mechanic..?

Extra benefit...  easy to label the vac switch and on/off status...

Industrial machinery has been using pressure/vac systems continuously... we don’t seem them often in consumer areas...

PP thoughts only, not a mechanic...

Best regards,

Wes, 

No I haven't. I would be interested if you find one.

Thanks for the link but while my IA normally has no issues with me working on a plane (just installed LHS panel with G5 and audio panel), installing non-approved parts is something he's not comfortable with. I already discussed that with him some time ago when testing automotive solenoid for function.

Purchased part can't be qualified as owner produced part so I'm in a search for a Brittain solenoid, at least for now.

I actually have no issue of having switch on a control wheel for temporary disengagement of PC; I pretty much have it on all the time except when maneuvering but having addition on/off switch on a panel might be useful IFR training (under the hood flying) or BFR.

No luck with posters above - I'm still looking.

Picture of solenoid:

[Igor_U]

Bump!

[Igor_U]

I'm still looking for solenoid before I send my control wheels to Hector for leather treatment.

There was one for sale on Ebay, included in a lot of servos but I missed it as it didn't show up in my search. Thanks.

[FlyingDude]

Why must the panel disengage be an electrically driven component? There's already an air-driven disengage switch with a hose going into the yoke. Can't you T that, route the branch to the panel and put a plug switch?

I would like to install 201 Style control Wheels with electric switch to control the PC system. I can't install the pneumatic Valve (PC "switch")  on new style control wheels

I wasn't aware of this caveat. Thanks.
