Caterpillar Diverter Valve

[kennyd]

I heard back, this afternoon, from Motion Industries' Account Rep/Fluid Power Specialist. He recommended this valve............https://www.motionindustries.com/productDetail.jsp?sku=00382745.
I am still a little vague on the subplate. He recommended a subplate with #8 SAE ports. I replied asking if they have a subplate with BSPP ports. BSPP is British pipe. It like our pipe threads, but parallel and not tapered. It isn't metric, like most folks think.
Thanks for all the help and replies.

That is not a "diverter" valve Brandi, have you changed your mind on the setup you want to use? Also, I'll take SAE/ORB over BSPP fittings anyway, unless you get adapters, getting hoses made in a pinch can be a PITA locally.

Here is what the rep from www.trauschdynamics.com wrote me today....We can supply just the valve for this. If you need to get an order going please let me know. Below are the components.
7120040 (1) this is valve body only
7120042 (1) this is 24vdc coil, DIN
7120007 (1) this is DIN connector
Selling price: $388.70/each
Lead time is 4-5 working days to ship
Valve rated for 4200 psi, will work great for their application
So this one seems to fit just what I want.
hugs, Brandi

Hi Kenny,
I still wasn't sure on that valve. I really didn't want one that needed a subplate. I guess I can go with just about any port fitting. I have to buy whatever fittings I need anyway. Discounthydraulichose.com has all kinds of fitting that convert to BSPP
My local hyd. shop always orders estra hose ends when I need a hose. So a new hose is just a 15 minute trip away during the work week and to 3 on Saturdays.

Heck an electric diverter valve is only a momentary device.
A simple resistor will make the voltage drop from 24 to 12 VDC and since momentary it need not be all that precise.
If you want to be accurate use ohms law to calculate the exact resistance required however a short shot of 24vdc wont hurt a 12v solenoid, in fact it will assure a positive shift.

Piloon,
Why add in extra stuff in the circuit, like a resistor, when you can buy the correct valve in the first place?

Brandi - have you really had good luck using BSPP? Part of my experience at Caterpillar was buying up companies, then "Caterpillarizing" the products. Loose, leaks and 'llectrics are 3 L's used at L - dealer complaints to the mother company because Cat dealers aren't paid warranty labor by the company. If a dealer has to make a arrant you call to fix a leak or repair an electrical connection for example, that was money out of their pocket. Caterpillarizing products from companies we bought partly involved replacing hydraulic connectors with the ones we found to be most leak resistant - SAE ORB (o-ring boss), hoses with ORFS (o-ring face seal), and 4 bolt flange for larger sizes, higher pressures. Electrical involved changing to Deutsch connectors. If I remember right BSPP takes a Dowty seal (bonded rubber inside a washer) and was something our dealers really hated. Then again maybe it was dealers complaining about something different. Being responsible for a team needling to redesign the products from an European manufacturer we purchased, I remember the rather large crew I needed to hire to do the redesign. The other company did not have the purchasing clout of a Caterpillar so the components might be a conglomeration of different type connectors - BSPP, GAZ, NPT, SAE, a dealer's nightmare.

I merely suggested that option as I seem to recall that either the proper valve was extra costly or not readily available or both, but then I did not re-read all the posts.
In that this is heavy equipment and not an aircraft, weight is not a concern.

MHarryE,
I bought the machine with no leaks at the fittings........and the lines I have replaced have no leaks. BSPP has a flat "washer" like fitting inside. No rubber inside. That's cool you worked at CAT! Bet you have tons of stories.

Probably the thing I miss the most is that in 44 years of engineering my job changed but a constant was working with the next generation product although my lady and favorite years were getting away from management positions where the people stress nearly put me in an early grave and instead traveling to all corners of the world to help people with major problems because in my years of experience I encountered about every failure mode possible. Having a colonel in South Carolina tell me that these 18 machines are leaving for Iraq Friday and if I haven't found a fix by then, I'm going with them. Sitting in a bar in Spain after disassembling a planetary drive and listening, as well as I could not knowing much Spanish, to the mechanics give their opinions about Italian workmanship - regarding the million pieces we found inside the planetary and if we had Spaniards design and build the drive, there would be no problem but no, we chose Italians. Or breaking for lunch at the dealership in Abu Dhabi and sitting down with a staff of South Africans, Pakistanis, Indians, Egyptians, Palestinians from the West Bank, a Frenchman, A German, and me - and there is no fighting, bickering, animosity toward anyone, just talk about things like a new restaurant that just opened, what did that crew do to dump that 988 loader off a barge and into the Persian Gulf and will we ever get it running again. So many things here I think, been there, done that, have the scars to prove, but why butt in and say anything - see if it blew up the same way it did got me.

MHarryE,
Wow, I would like to sit around a fire listening to your stories! Can't help it, I got a mechanical mind instead of a home decorating mind!
Merry Christmas hugs, Brandi
