Valves from ASV-Stübbe are resistant against aggressive media. PVC-U, PVC-C, PP, PP-n, PE, PVDF, PTFE and corrosion resistant metals are used for the production of our ball valves, diaphragm valves and diaphragm gate valves, butterfly valves, pressure control valves and solenoid valves to respond to individual product requirements of our customers.

The sealing materials vary depending both on medium and stress. Here, EPDM, FPM, CSM, NBR, PE and PTFE are used. The required interplay of valve material and sealing depends on the chemical concentration and temperature of the media conveyed; please refer to the ASV resistance list.
