Guess my valve!

FIRST General Forum

i was hoping someone could tell me what the product number is for this valve, where i could find information for it or post the specs themselves.

as a follow up question, is it appropriate to control this valve with a spike?

I think if it isn’t labeled, it probably isn’t legal (pressure rating)?

It probably wants to be controlled by a relay output on the CRIO, and shouldn’t need a whole spike. Most industrial solenoids like that will want 24V, but it’s hard to say until we figure out the part number.

Any view of the other side?

Well it’s a Festo but we will need to see the side with the part # to know if it’s legal.

that’s what i thought,

here is the other side

the product number has been rubbed off, that’s why i asked if anyone had the product number

Why didn’t you post a photo of the other flat side?
The one with the rubbed off part #.
You have photos of one side several different times.

the black smudgeing is all that’s left. if i look real close i thin i can make out an “M” and either a “5” or an “S”

That looks like it’s a VPLE18-M5H
4/2-1/4

They came in the Kits years ago, but that particular model is no longer manufactured.

is it legal?

I’m not your robot inspector, so I’m not the person to ask.
Chief Delphi isn’t an official source.
Without a part number you have difficulty proving that the solenoid meets the Robot rules.

There are other models with the same form factor that would not meet the pneumatics rules requirements, and I’d have to double check that valve’s specs against the robot rules.

well thanks anyway, you were all a huge help.

I’d have difficulty believing that isn’t an R77 violation as well.

As to legality, it was asked on Q&A

  • Q419 Q. Are the older KoP Festo VPLE18-M5H valve legal for use? The specification from FESTO are obsolete, however these valves were legal in previous FRC seasons.

    A. To be legal for use, any pneumatic solenoid valve must meet the requirements of all ROBOT Rules, specifically, [R78]-C. Per Section 4.1, the Team is responsible for proving a part’s legality during Inspection. *

What’s the R77 violation?

I* don’t believe a solenoid with a rubbed-off label meets the definition of original, unaltered condition.

*Not an inspector or the GDC.
