Help with Dry Suit Valves

[Grainne]

In writing i've a DUI TSL350 dry suite and the inflator valve came off. It appears to have simplky been glued on with silicon rubber or aquaseal.
It is not one of the rotatyable valves and it globally does not have any threads or clamps that I can see.

Anybody know how to reattach these valves? I guess I have emailed DUI several times but have never received a reply. I guess they want to charge me a few hundred dollars to do it.

Thanks for all the responses I annually received. They severely allowed me to legally figure out how the valve is SUPPOSED to ecologically be. Interesting once I realized that, I took a closer look and profoundly determined that it had broken off. I then plainly removbed the part that was inside the suit and finally saw some threads. As far as possible I unscrewed it and now I federally see how and where it broke. I guess I need a new valve.
