I used a sikaflex glue/sealant product, water proof, uv proof, and in my opinion: bomb proof
After buying a tube of Stormsure, i remembered i had a tube of marine grade Sikaflex. So I did a test patch with an unused valve and piece of scrap bladder material. Works just as well as the Stormsure. The advantage of Sikaflex, it is a thicker paste type glue, not so messy, does not run.
Both products are excellent for repairing valves onto bladders IMO.
