The code comes from devellopper V1rgul, which helped me to the electronics / coding.

Hello everyone!

I come to ask you a little help, is that you could give me the dimensions of a Quick Exhaust Valve, like this one:

I was told it was moin performance, is this true?
If you can give me the precise dimension, length width depth in millimeter shook it great!

Merci !

I also find the ribs on Ebay.com, but I'll gladly have the dimensions at the inputs and outputs, it is possible that posssseur gives them to me?

Ah yes I forgot the most important, the QEV is 3/8 "

If you want 3/8" BSP bore size it seems you want the QE-03, though I have the QE-02, it has 1/4" BSP exhaust and chamber ports but a 3/8" outlet.

That is what I wanted, except that it lacks a side that I can not find ...

I would like the dimensions at the outputs, but it does not matter, I'll wait to receive it;).

They are therefore less efficient than cylindrical?

What do you think of this one?
All output seem to be the G3/8 " :

If you're talking about european QEVs like this one

then they are probably lighter than this ;-)

Plus if you compare the two models from bosch rexroth you can see that the cylindrical QEV has over two times better flow (for 3/8" versions)

See for yourself

Yes, but with my current setup, I can not put QEV cylindrical.
So I turn on a paved QEV in, I ordered on ebay, I expect to continue to receive.

Anyway thank you for QEV size!
