Technical data
Working medium
Corrosive, inert, gaseous and liquid media which have no
negative impact on the physical and chemical properties of
the body and diaphragm material.
Working medium temperature
Valve body PVC-U
Valve body ABS
Valve body PP, PP-H
Valve body PVDF
The permissible operating pressure depends on the working
medium temperature.
