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. MG = diaphragm size
