Air Cylinder

Is it Okay to use This kind of Air Cylinder

[Tristan Lall]

No. R76 requires a minimum rating of 125 lb/in².

(That general style of air cylinder appears to be allowable.)

Are Any of These Okay To use.

Weird. There's an exception for solenoid valves rated under 125psi, but not for cylinders. Anyways, Tristan's correct, that's illegal as it's only rated for 100psi.

This Is not the Actual Cylinder But I was wondering About The Style. I don't really Know about This Style. Its Has One Air Input Hole and i didn't know if it was okay to use.

(Note: The Maximum Working Pressure is 247 , On our Cylinder )

There is nothing in the rules that prohibits the use of single-acting pneumatic cylinders.

Single ported spring return cylinder that's rated over 125psi? Sounds like an air cylinder that's rated over 125psi to me.

For future reference, that's a spring return cylinder. Air goes in, the spring compresses, the piston moves. Remove the air pressure, the spring shoots the cylinder back to its home position.

As for whether it's OK to use per the rules, I can't find anything prohibiting any type of cylinder (see R78-H) as long as it's appropriately pressure-rated and unmodified.

Thanks For The Help, Also Do anybody know were i kind find out how to connect the single-acting pneumatic cylinders to the Single Solenoid

(Note: This Are the kind of Cylinders We are using http://www.amazon.com/SMC-NCMB075-02...s=air+cylinder

To use a single-acting with the solenoids usually seen in FRC, just plug the tubing into one of the two outputs of the solenoid and put a plug into the other output.

How Can i Plug it.

With one of these if your solenoid has threaded connectors or one of these if the solenoid has built-in push-to-connect fittings.

Art,
I've seen 5/2 valves out there in FRC. That's actually the style that Vex sells. A 5/2 valve is always sending pressure to one of the output ports. You'll need to plug one of the outputs in that case, or you'll end up dumping pressure to atmosphere when you're exhausting the cylinder. You need either a double solenoid 5/3 center exhaust valve or a single solenoid 3/2 valve.

Okay Thanks, Also so is it okay to use these Cylinders: http://www.amazon.com/SMC-NCMB075-04...matic+cylinder

You should be able to answer that from what we've covered in this thread, so why don't you tell me what you think the answer is and why, and then I'll tell you if you're correct. Teach a man to fish and all that.
