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 PP / PP-H
Valve body PVDF
The permissible operating pressure depends on the working medium
temperature
Temperature in °C
(plastic body)
Valve body material
PVC-U Code 1
PP / PP-H Code 5 / N5
PVDF Code 20
Data for extended temperature ranges on request.
Please note that the ambient temperature and medium temperature generate a combined temperature at the valve body which must not
exceed the above values.
All pressures are gauge pressures. Operating pressure values were determined with static operating pressure applied on one side of a closed
valve. Sealing at the valve seat and atmospheric sealing is ensured for the given values.
Information on operating pressures applied on both sides and for high purity media on request
