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.
The valve will seal in both flow directions up to full operating
pressure (gauge pressure).
Operating temperature (drinks filling)
Operating temperature (other applications)

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.
