MG = diaphragm size
* Actuator sizes _DL, _DM with weaker spring set for operating the system with low wear on the diaphragm and
for vacuum 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.
