Pneumatic Solenoid source

We need some additional Solenoids...
We checked with FESTO but they are quoting
$100 each.... no special deal for FIRST teams...

Anyone have a better (cheaper) source for these or any other cheaper legal alternative?

Thanks for the help!!

Re: Pneumatic Solenoid source

look at the COTS section of the manual.. but i think if i remember right it says as long as the solenoid matches the specifications it can be used

Re: Pneumatic Solenoid source

Do some swapping with local teams who aren't using pneumatics this year.

We picked up three that way last year.

Re: Pneumatic Solenoid source

That's a good idea... we will try that..
Not only are they expensive but the lead time for shipment is also too long...

Re: Pneumatic Solenoid source

Doesn't help much with price, but AndyMark sells a Festo valve kit now:

Re: Pneumatic Solenoid source

Not to derail the topic, but does any one know where to get the single value festo?
Thanks in advance.

Re: Pneumatic Solenoid source

I've actually been much happier with SMC Solenoids:

Easier to get as well.

please note that these are 12 vdc and not 24 vdc like provided in the kit.

Re: Pneumatic Solenoid source

One of the FIRST Choice options was some pneumatic fittings from Nitra, through Automation Direct.

AutomationDirect has several solenoids on their website and the prices seem reasonable.
(EDIT - These SOLENOIDS do not meet the 2011 rules.)

The site tells you immediately if the item is in stock.

Re: Pneumatic Solenoid source

Question:
<R66> states a maximum Cv of.32.

I cannot find anything on the FESTO page that gives this rating for the VUVG valve that AndyMark sells or was previously provided. Does anyone have the spec sheet for this valve?

Most of the valves I am finding have higher flow rates than .32.
Is this changeable with a fitting in the out port of the valve?

I'm not an inspector but if I were these valves wouldn't pass. Not only is the CV more than twice the allowed rate they also are only rated for 115psi and would require a second pressure relief valve on the low side.

As long as you stick with the VUVG M5s you will be legal.

The larger M7 are the ones that flow more.

On the pressure side, these are on the downstream side of the regulator, and operate at 60 PSI.

Although since they were in a previous KOP you could assume they are legal, but I cannot find any documentation on the specs to show that. I don't think it safe to assume older KOP items are legal to current rules (think FP motors ...).

B. Solenoid valves with a maximum ⅛” NPT port diameter, and a maximum Cv of 0.32 (if non-KOP valves are used, the team will be required to provide part documentation validating that the valves meet these constraints).
Solenoid valves that are rated for a maximum working pressure that is less than 125psi rating mandated above are permitted, however if employed, an additional pressure relief valve must be added to the low pressure side of the main regulator. The additional relief valve must be set to a lower pressure than the maximum pressure rating for the solenoid valve.

The valves are included in this years rookie kit and are the same as last years valve. The only difference in what AM is selling is the coil voltage.

AndyMark is selling the M7 valves. Are you saying these are not legal per <R66> B?
