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. Higher operating pressures on request.
