JDM
Please supply us a link, to the actual manufacturers spec, detailing that the "flow orifice" is 16mm.

I see the "chart", but is without actual manufactrer verification... which is what I go on.

I cannot see it from the link you provided in post 194, nor do I believe for 1 second, that is correct.
I have speced solenoids, and designed hydraulic circuits for decades, and inlet/outlet thread sized valves of this nature NEVER have an orifice that size.
I would say it is closer to .160" diameter, finding a solenoid with a 1/4" orifice thru, is difficult even, and I base this on my job, and the fact I researched this all a lonnnnnnnnng time ago, when Gary was looking for a valve to use. I could not find a single 12v small, 3/8-1/4" npt valve with an orifice over 3/16", and that one was expensive, high buck one.  Even on 1" npt valves, you would be hard pressed to find an orifice 3/8" or roughly 10 mm.

I made my conclusions based on specific product literature from the manufacturers of the valves, with specific attention to "delta P" pressure drops, at atmospheric pressures.  I found none I was excited about, if I had, Murph would be selling them, I guarantee...

Not going to happen.  i am done. Sorry for being short with you MOB but i am out of the business. jd

Ok,
I only asked because both Relian and Woljay, come up goose eggs when I search for them as a valve manufacturer...
Sorry to have discomforted ya, but I tend to be a bit aprehensive when mixing fuel, motorcycles, and electrical things, without a bonifide company name to.go to in the event of... some scenario if there is a failure.

Ride safe.

Richard, you have been around here for about as long as I have, and just about as big a pain in the a** as me. Why don't you turn this project into a plug and play for the C10. I am finished with this, but I will give you all the help I can, and all the info I have. The reason I am willing to help you with this is I know how well it works, and I also know the C10 needs this mod. I  hoped I made it very clear that there are several other benefits you can get from this mod. If you look at the way these solenoid valves are designed, you will see that the electronic components have been sealed in a metal can and are sealed very well. I am not sure this valve is advertised as a non-arking device, but they sure look like it to me. You find these all over in gas plants and refineries. If you purchase this valve from Amazon and find it does not meet the spec. as stated in the ad, Amazon will give your money back in the form of a refund along with any shipping costs.     
  https://www.amazon.com/RELIAN-Electric-Replacement-Pipelines-Applications/dp/B01FU3Y4VW/ref=sr_1_fkmr0_2?s=industrial&ie=UTF8&qid=1501720153&sr=1-2-fkmr0&keywords=2w16010+12v+solenoid+valve+3%2F8 

Rich, the part # on this valve tell you that it is 2 watts with a 16mm orifice, and 10mm pipe threads (thus 2w16010). And if you don't get that, they sent you the wrong valve. Solenoid valves are a bit like car batteries, there are only a few manufactures. But, if you were willing to buy enough batteries, I bet you could get your name put on one, and if you buy enough solenoid valves you can have your name on one as well. You might want to call it SPARKEY. If that gives you some concern, get a valve that is ANSI approved. It's a bit overkill in this case, but to each his own. https://www.google.com/search?q=ANSI+approved+solenoid+valve&rlz=1CAACAG_enUS704US712&oq=ANSI+&aqs=chrome.2.69i59j69i57j69i59j0l3.8423j0j1&sourceid=chrome&ie=UTF-8     

Rich, were you not the one that used to make curb finders for the Connie? This project would be a lot more fun and you could get to know another A-HOLE. Hell, you might even take a liking to me. I am just saying.....

all one would have to do is a controlled timed flow test between the stock petcock and the lifting valve. i'm not seeing any Cv or gpm ratings mentioned, but this is also what i do for a living now (actuation/valving/automation)  that's the sure-fire way to know if it flows enough. ;) as long as the flow is equal or greater than the petcock, will be ok. has anybody actually flow tested these things? also, it can be located under the seat, doesnt matter, as long as its below the fuel level in the tank. that being the case, you can run a bigger valve to get the orifice you need for ideal flow and just neck up and down for the lines. my .02

  Let's see!!

   OEM petcock ( on my second one in 23 yrs), clean fuel system and overflow tubes. The real clunker is the float needle that gets stuck open. IF you don't have overflow tubes you may not know if a float needle is open and fuel is filling your cyl. Hit the starter button with raw gas in the cyl. and "BANG" !!! A BENT ROD! DESTROYED ENGINE!! :'(

  Get some overflow tubes to at least warn you of the problem. May bum you out to see gas on the ground but at least you know you have a problem!!

   Let's not get too complicated trying to fix a simple thing. My fuel system has never failed  ::) but IF I see fuel on the floor or ground I KNOW I have an open float needle and a bad petcock. "DON'T TOUCH THE DAMN STARTER BUTTON!!!!

i think the consensus is yes, over flow tubes will remove the riskl, thats been established. however, there are other and additional options, trying to be open minded here to other options.

 personally, i like the manual valve, i'm used to them. i'll add tubes later. but i never assume the vacuum petcock will work properly all the time. ive had too many bikes have them fail on me. plan for the crash, not the ride. i mean, in 25 years of riding i crashed once. but i planned for it every ride by putting a helmet on. and, it saved my life. a tiny flake of rust on the o-ring on the diaphragm plunger is all it takes to crash the system. and, fwiw, i have seen bikes with vent tubes still hydrolock. the h1 i was referring to filled the LH cyl on the sidestand and blew the crankseal out.  super rare, but happens. 

from an engineering point of view, i like the electro-petcock.. my 74 moto-morini actually  had one from the factory.

The 12v goes through a coil of wire to create a magnetic field that acts on a moveable ferrous slug. There is no make or break contact that could cause a spark.

I rolled em quite a bit over the last 100K with the solenoid valve and no tubes, so far so good. :nananana:

I really want to back out of this nicely, without p/o ing anyone else off, because of the time I spent trying to find an industry rated and certified for use with gasoline, solenoid, with an orifice larger than 1/4"... to which after a hundred or so hours, I could not do, well, unless I wanted a valve the size of a brick, that had 1"+ threads, that cost a couple hundred....like $400+ dollars.
When I say rated, I mean API, UL, CE, and ANSI.
An un rated valve, manufactured in the USA (not China), and holding ratings and sold as such isn't an option for me. And a foriegn valve, with no ratings?
I wouldn't use it if it were free.

Now, I fully understand how this solenoid works... I also understand the coil that operates it. I also know that while the valve is "open" there is always a current draw on the coil, its inherent to its operation, and is actually the most common complaint about 2 way solenoids in systems... they always eat powernwhennoperating. Not a lot of power, but just the same... and that generates "heat", no getting around it... and mind you, the thermal rise may be minimal, and not a concern.. which it isn't...
The concern is, the two stranded wire leads that enter the canister, and attache to the fine coil wires which are wound on the bobbin...
Without a rating, you have no idea, unless you take it apart, how they are attached...
I've seen them soldered and covered in shrink tube, crimped together with ferrules, equipped with quick disconnect plugs and sockets, all sorts of means of wire bonding. The best quality products actuall bod these wires and "re-dip" in the potting compound, to prevent wire fractures at the joint.
The el cheapo ones, the $25 ones, commonly are the crimp and shrink tube ones, with the wires unsupported...
I can't count the number of this type I have replaced on machinery in the places I've worked, when they were subject to constant vibration and jolting slams, generated by the machines, punch press gripper circuits, clamping devices, location devices on agressive machinery..mostly all were 2way units, at 24-120vdc,
And most of those were only pneumatic air valves...

I won't spend any money on buying one for "evaluation", even tho the ad says "ok for fuel" because that's Amazon speaking...and they won't disclose the manufacturer..  I can believe its rated for air, and water, but when they get to the "gas" statement, it needs specifications, true manufacturers tell you "what gasses" whether they are "inert", like helium, carbon dioxide, etc... then the rating changes, "natural gas, and LP gas" are different, and require certs.. then you get to "oil".. again,... "light oils" refer to low risk,nlike some hydraulic fluids, and mineral oils.... no big deal,   but jump to "fuel oil" and its a high.standard to meet, price on a rated valve is well over $100, and climbs rapidly... "gasoline" is a whole new ballgame... do a.search, a real search, and find manufacturers with "gasoline rated valves", not amazon rated valves...
Start with the industry standards like ASCO /Emmerson

Sorry for the rating thing,. Its just been a part of my employment necessity, as a los of life or property, in a product I designed, was not an acceptable option.

To this day,.I.still feel bad for the engineer that said. "Don't launch that space shuttle.... those rings weren't rated for that low temperature..."
Who finally ended up taking his own life, because of the gult he had when his "higher ups" forced him to back off. Sad.


Sorry, I had to correct that, I thought he killed himself, he didn't...

and this...

Great idea on that shut off valve.  But, isn't that valve for 1/4" fuel line?  I believe our fuel line is 5/16".  I would be worried about the restriction it's adding, even though, you have never had any issues with fuel starvation.  But, you also say most of your riding is in the mountains and I think the majority of fuel starvation issues are experienced at constant highway speeds.  With that said, there are 5/16" shut off valves similar to that one on Amazon and Ebay, but they cost a little more and are brass.

Well, I just pulled out one of my failed petcocks for inspection and using a digital vernier caliper from Harbor Freight, I measured the inside diameter of the tubes feeding fuel from the gas tank, and I can say with certainty that they are in fact exactly 1/4" (or 0.2500" +/-0.0015"), so I can see where a 1/4" solenoid should be a good match.

I may try the solenoid just for fun in addition to adding my own overflow tubes when the snows arrive again next month.  ;D

rated for fuel and enough flow, looks like viton or fkm seats, both fine for fuel, and in the review states it certified ISO 9001-2000. no way is the concourse going to outflow this:

fwiw.. MOST valves are foreign these days. we (my company) are the guys that sell to the distributors, as an fyi.  and no, this isnt one of my products, we don't typically do lifting valves..

FYI:  ISO 9001 is a quality "MANAGEMENT" standard.  It has nothing to do with the product.  To get ISO 9001 certified you must prove to independent auditors that you have documented all of your processes and you follow released procedures for such processes.

im well aware of that, but it shows a process exists and is being followed. beats nothing on the label. a ce or nema rating is not nec cheap, and may not be needed to whoever they sell to. but iso shows consistency in manufacturing to (whatever) standard is.

Mark, you are dead on, look at it's part No.  2W-160-10-12V. Maybe you need to develop this into a plug and play system. I will make you the same offer as I did for MOB.  You would be helping to keep the old girls on the road for a long time, and that is a good thing.

Mark, you are dead on, look at it's part No.  2W-160-10-12V. Maybe you need to develop this into a plug and play system. I will make you the same offer as I did for MOB.  You would be helping to keep the old girls on the road for a long time, and that is a good thing.   

OH CRAP its the same valve. lol. :) i didnt even realize it at first, prob come out of the same factory. :)  i know, for a FACT, we get solenoid valve coils (spool valves) made at the exact same factory as the ones that have the ce and ul listing, we order both. cost is different but they roll right. off. the. same. line. Im not saying this is exactly the case with this, but i certainly wound not be surprised.

Mark, we are talking about a whole new fuel system for the Connie. I think you should take to where I could not. I will help.

i'll look into it for sure around the end of the summer. i have some road trips planned for my new bike first. TBH, i actually have a line on a tiny rotary actuator/ball valve that could be used with a 1/4" full port brass or stainless unit.

im well aware of that, but it shows a process exists and is being followed. beats nothing on the label. a ce or nema rating is not nec cheap, and may not be needed to whoever they sell to. but iso shows consistency in manufacturing to (whatever) standard is.
See, this is why I am so critical, what you just said, is completely incorrect.
Having been in charge of my engineerings ISO programs, and after time and MUCH expense, we found it didn't mean squat as far as wht we manufactured or sold as a finished product... it was merely a "look at us, were ISO certified..." labeling, which has zero to do with "product quality or compliance"...

All it means is that books and files are created, and kept, waiting for anyone that wishes to take the time, may be perused and compared to the components utilized in the manufacture of that final product.. simplified, its lists of people you buy parts from, keep the name, address, dontact, and part number, along with a description however brief you want to make it, on each person you buy crap from... it is NOT a certification of quality, correct form fit or function, reliability, or responsibility of failure of a component based on anything other than it is a list of parts and vendors.
It also allow companies to keep "approved vendor and alternate parts interchange" at their whim...case in point, you buy 6 different valves, form, fit, and function typical.... 5 of those valves are UL/API/CE...ASPCA :rotflmao: certified, and cost $200 each... one valve is totally junk, costs $3.25, and has the same dimensions and characteristics....   you start out with great intentions, because you flagship product, that originally used the $200 item worked perfectly.. then, cost cutting comes along, and you swap them for the el cheapo valves... all fine and dandy... ISO could care less, its your liability... the auditors have little or no clue as to what exists in your manufactured product, just what the paperwork says, and maybe what items are on your inventory shelf...maybe.
But, if your PRODUCT was UL, CE, NEMA, or API certified, and you were granted rights to apply those certs to your product label (which is what we in industry pay big $$$$$$ to get done, because those DO mean something, and its found you swapped parts.... your company gets severly flogged, and whomever was responsible gets fired... AND you loose your certifications...$$$$$$$$$$ ..... I know this, I have submitted and had litterally a hundred products go thru various UL, ETL, CE, NEMA testing, in order for them to meet the certs, and wear the branding iron of same.

So, I kinda laugh about this ISO thing,
Its kinda like people I interviewed for positions in engineering, that right off the bat tell me they have an MBA.....  :rotflmao: :rotflmao:  my retort to that statement is usually, "oh, I'm really sorry about that..." ;) :rotflmao: :rotflmao:

like anything, it depends on what you do with your certification. insult me all you want, but i'm well aware of the fact its a documentation process and never did i say it had anything to do with quality, just consistency  . laugh all you want.  this comment sums it up:
shows consistency in manufacturing to (whatever) standard is. the part of procurment would also refer to the testing we did as it was part of the procurement process.  when i was running a division of Desoutter (Atlas Copco company) a few years ago, and we were audited repeatedly year after year after year, we , in our iso documents, showed suppliers items were sourced from, method (at least show we had documentation) of procurement , etc. so, if there was ever a question at hand we could show line of responsibility of fault.  IF you aren't willing to have this, you're probably running a shady operation. they will typically ask for the documents papertrail all the way back though. we always did, and never even got flagged, not once. no manufacturer has any gain in supplying failing items, and those valves, in question, are all over the place. i seriously doubt they are all junk. look at the reviews on the link i posted.

ps.. show me the certs on an oem petcock please.
