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 Major UK Manufacturers 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 cylinder 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 need some Engineering help.

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’ve been working with automated machinery for a long time, but haven’t learned everything yet and need help with the workings of a solenoid valve? 😉 I’m currently mentoring a high-school robotics team, and our robot uses a single-acting cylinder operated by a solenoid valve. The cylinder needs to run at 20-25psi for proper thrust, and it works fine at that. But, the valve doesn’t work at such low pressure. It hit me that the valve might be a piloted type. I want opinions on whether I understand how it works, or set me straight. I am thinking a piloted valve is a smaller valve operating a larger valve. That the solenoid drives the pilot valve, which ports air to move the larger valve. This would explain why we hear the solenoid click when energized, but no air output when used at low pressure. Do I understand this correctly?

Secondly, are piloted types more common than non-pilot? What are the advantages of the pilot type?

Thanks for all replies!

Can any help me the identification of the valve fitted on my tractor. the valve is for the air assisted steering made by auto steer of Leeds. I believe its a relief valve. any information would be great.

Hi i hope you can help? I need help with vacuum cups to design a system to suck out a plastic component from a metal cap. i have tried asking our local supplier of valves and they cant help unless i know exactly what i am looking for! Any help would be greatly appreciated.

Hello everyone,

I am in need of some help and guidance here.

What I’m looking for, is one piston that has a stroke of 6 foot, has a 3 ” bore and half inch ports and runs at 300-1300 PSI.

Does anyone know of where I can purchase these?

I’m also looking for 2 identical smaller pistons with a stroke of 12 ” or so and run at 10-60 PSI or slightly more.

Any help would be most appreciated as I’m finindng it difficult to obtain the larger piston I need.

Although from seeing similar designs online, I see some companies that do sell products near identical but they run at lower pressures and seem to do the same job of jerking back a weight upto around 220 lbs or lower.

Thanks to you all in advance.

Cheers. 😀
