Burkerts

[woody]

They dont seem to be listed as a std option.

They are no option, and the Burkert coils are bigger than standard pneumatic coils,and smaller than the hydraulic ones.

Otherwise I would buy Burkerts with 12V coils anytime

If there is intrest in my voltage booster I can whip up another batch. Just mail me
They look like this: http://www.bugs.nl/media/album/view.php?&path=L3Byb2plY3RzL3ZvbHRhZ2UtYm9vc3Rlci9 JbWdfMDg2NmIuanBnhttp://www.bugs.nl/media/album/view....Z2UtYm9vc3Rlci 9JbWdfMDg2NmIuanBn
Ive also made some luxury models pored in resin to make them shockproof

Any of these suitable Mario?

I have bought a Burkert 12 v coil for my 5404.

Got a reference number Phil?
It sure would help to run 12v coils.

Valves can dry out over time and stick...

Ive seen a small amount of hydraulic oil make a big difference in a pneumatic system by lubricating the valves.

However, I would point out that it is possible, depending on the valve material, that the oil could react with the valve seals.

Dont use combustable lubricants like WD40, or normal oils, as these could combust under the pressures involved...

CO2 is on the other side a perfect fire extinguishing gas.
I never encountered a dieseling effect, and I dare to say that some of the rams I did build are strong and fast enough to get that effect.Actualy not. In a CO2 system there is no free oxygen to react, and on the non pressured side of the piston we dont want to have any pressure build up.
I would be surprised if we get a diesel effect in a good designed and build Full pressure CO2 using system. Is that a Gravity or a Dantomkia setup.

I use the very sticky molycote 111 silicone grease in my rams. And the Burkert valves are equipped with sealing materials that can stand a lot off chemicals. But Silicon grease/oil is mostly the safest bet you can make.

Woody, there are a couple of numbers. AC10-Z3-5-38AA (I think. The last few were a bit hard to read.) and 130104Z. The coil came from Burkert in Sydney, Australia. Your local Burkert should be able to help you.
