Well obviously you didn't tell the pilot to work as a semi auto valve.
He's obviously confused.
Seriously, give us some details, which pilot valve, chamber or pilot filling, homemade piston valve or commercial QEV?

Is your air tank directly connected to the QEV? Here is a diagram of a QEV semi auto system.

put a spring behind the piston so that it closes by itself
@zues: LOL

Alright ! ... The Pilot is where it dumps the air to open the QEV valve through a blow gun (Rated at 150psi) ... the pilot has a nut that can be undone and tightend to measure the bursts of air but at the moment the pilot comes out and blocks the blowgun which is good but my piston in the QEV is staying open and losing all the air from my cylinder ! .
Zeus ... im not a complete retard please be nice !

yes so put a spring inside the QEV so it shuts down by itself!
put a spring at the pilot side so it presses to the exaust port

You also need an equalization hole in the diaphragm.
And I am nice, you just gave the most vague question I've heard in quite some time.

is that a homemade piston valve?
i try to get multishot with my homemade piston valve like that before
it's suck
because the vlave's sensitive depend on your piston quality , want semi auto the piston must perfectly fit, moving easily, and good sealing face, of course
so , buy a qev , a blowgun , push it sightly..... something like BTB say in some thread , i don't remember
or make a hammer valve
it's easy to make too
