After some research it turned out that the materials being processed, whilst highly corrosive for st/st, were compatible with certain grades of Peek-like polymer, and indeed that a silicone seal was also suitable.
We were able to propose a custom valve with Peek body, Hastelloy C-22 leaf and silicone seal. This has the advantage of being substantially cheaper and much lighter than a full Hastelloy valve would be.
