What happens if a 110VAC 60 Hz solenoid is connected to a 24VDC supply. Will it burn or simply will not operate (but will not damage)?
how about the 24VDC coil supplied with 110VAC?
thanks in advance

We need High speed sorting valve at about 1ms of operating speed for food grain sorting application. (other than festo MH series).

I'm a builder of Big Bore PreCharged Pneumatic Air Rifles.

In my quest for more power I've begun doing some informal research on ways to increase the output-psi without having to increase the existing input-psi I'm working with.

As an example: I presently build a PCP Rifle that can launch a projectile at 850 Feet Per Second by using a burst of approximately 400 psi of compressed air.

The entire sequence takes place in about 7 to 8 milliseconds. I would like to be able to decrease my input-psi by half of that amount while still maintaining my present level of output-psi via the use of an Air Intensifier or other specialized pneumatic fixture.

This would allow my PreCharged High Pressure Air Tank to generate a more constant and longer PreCharged condition before needing to be refilled.

The main benefit of finding an appropriate and safe Pneumatic fixture would be to use that same specialized pneumatic fixture or fixtures to increase the output-psi/power while keeping my existing input-psi at a safe level of pressure with respect to the current metal parts I'm using.

Although I have a fairly good grasp of what's safe and what's not safe when it comes to working with High Pressure Air systems, the field of Pneumatics is not my specialty; so, I turn to the experts In Search of Pneumatic Wisdom.

I thank you in advance for taking the time to read this and also for any help you may be inclined to share.

Hi,
Can anyone help?
I have a provisional UK patent that can be used in pneumatic or hydraulic systems.
I am looking for a manufacturer that will observe UK law until I get a full global patent.
I will ask any such company to sign a Non Disclosure Agreement and then they can look at my invention for free.
I would prefer the company to be as big as possible so that it can defend the patent (I will include this in any agreement).
I would be grateful if you can advise me which UK companies to approach.
Thanks,
Alex

Hi Everyone

Does anyone know of any pneumatic cylinders which are modular i.e. no need for flanges to create a pick and place.

Regards

Dear ,

We are Polyurethane tubing manufacturer. But I got an inquiry about Fractional tubing. I searched on google.com. It said, Fractional tubing is an Aluminum tubing.

But my clients said it is flexible tubing.

Who could give me some information about Fractional tubing?

Many thanks ! info@samlongda.com

need some help with pneumatics cyliders, I've got a pneumatics cylinder with a stroke of 500mm and need to lower a piece of material in 10 stages, so this means first stage it needs to be lowered 50mm and then without going back to its original position lower it another 50mm and so forth till its lowered 500mm. Any help will be much appreciated. It doesn't have to be with pneumatics any other suggestions will help.

Thanks

we have a solenoid operating a pneumatic spring return cylinder, cylinder retracts under pressure and spring returns when pressure is off……the problem we have is a couple of seconds after the spring advances the stop when it should, the stop shoots down and back up again when it should not……any ideas as to why this would happen

Thanks

I am using an air cylinder of 100mm bore operating at 6 bar. The force from the catalogue states it will generate 4524 Newtons yet I cannot fully press in a 4mm steel dowel pin (4.004/4.012) into an Aluminum part of hole of dia 3.983/3.993 mm by 11mm deep. Anyone have any idea what went wrong?

I'm working on a project with several aspects using compressed air, all of them sharing the same tank. There was a failure on one of the components which caused all air to bleed from the tank and of course the compressor couldn't keep the pressure up so the whole machine shut down. Is there some sort of device we can install on each circuit that can prevent this in the future? I'm picturing something that will allow a reasonable air flow at all times, but in the event of a completely open line it would shut off that circuit. Does that sort of thing exist? Thanks!

I am looking for a seal kit for an older HERION Valve.
The number on the valve is: 232 : 146R There is a letter R above the number.
The valve is used on a press machine,
Any help would be greatly appreciated,

Hello all,

I am in a predicament at work, and I thought that some of you might have some clever ideas about how to make my day better!
Here is the situation: in a current telecom project, I am using two 25mm heavy duty (with two pins in addition to the rod) cylinders, distant from about 500 mm from each other. I could not use a single cylinder since I have a lot of connectors to connect (the cylinders pulls a device towards test connectors).
I have clearly underrated the speed difference problem between two cylinders. I thought that, considering the forces at stake, and the guiding pins helping, that any mismatch would be "eaten" by the cylinders themselves. Well, it works in most cases, but it does become problem at some point, randomly. One goes quicker than the other one, and both cylinders stop due to the side load they are subject to.
I could redesign quite a lot, to better link mechanically these cylinders, or by having some kind of dampener that could take care of the non parallelism, but my project is in a very critical phase with virtually no time at all. Only a few days to have a concrete solution.

It is pretty obvious that the problem disappears when the cylinders work at high speed. But since I test connectors in place, I must be "gentle" with them. But my first idea is still to make the cylinders go quickly enough to prevent the current trouble, but not so quick that the connectors are worn out quickly.

But thinking about the speed of the cylinders, I thought of the other way around. Since the pins in the cylinders allow quite a lot of side load, it might just work to make the cylinders move very slowly. In that case, one will not "have the time" to go first all the way until getting stuck. It would so that the other one has enough time to move before the first one get stuck, and this during the whole pulling process.
Am I totally dreaming?

Another obvious thing is that some preloading on the cylinders help them to go down well. I haven't tested with my device on (it is a 15 pound device) so it might just work directly, but I was wondering if any of you guys had similar "preloading" experience.

And at last, I cannot be the first one to encounter this problem. A few of my colleagues have had it before, but none of them really solved it (they all redesigned heavily). I cannot believe that there is not one "somehow quick" fix considering that the whole thing is working already, and it feels as if I am so close to something stable.

Oh, anf for those wondering, I use separate speed cylinders and vavles for each cylinder, that I tune until the cylinders go at the very same time. But it is only an eye tuning, those tens of seconds that I lose might be the very reason why the whole thing is not stable after a few minutes.

Any idea / support would be greatly appreciated! Pneumatics rock, but this has got to be one of their major drawbacks.
Thanks a lot to everybody reading this message!
