You should search for producers of diaphragm valves. You will find your answers there, with references to typical sizees and fluids.
The most sensible use is for difficult fluids obstructing normal valves, clogging or with a mix of fluid and drystuff, often with small and large particles etc, or difficult chemical compositions. could find (with certain practical and cost limits) practical solutions with diaphragm valves.
You will also find that the best producers offer a combination of different material layers, vowen and non-vowen, reinfosrced and not reinforced, adapted for different chemical, temperature and general fluid characteristic. One or several alyers could be polymer or something completly different
Apart from this: Any plastic material will swell and alter characteristics over time depending on fluid and temperature. This why you will find different available solutions with different qualities and upbilding with a multitude of layers (like a tire construction for different purposes),
Wrong selection of material: cracking, dissolving, hardening or swelling prior to normal expected lifetime. Cure: select other materials and construction.
