There is no reason to specify DIN 19213 instead of IEC 61518

IEC 61518 (DIN EN 61518) is the global standard for Manifold-to-Transmitter Flange Connections. This standard has been issued in 2001. IEC 61518 is based on the German standard DIN 19213 (latest revision 1991 before superseded by IEC 61518). So, basically DIN 19213 is not anymore used with the exception of revision 1980, which is still specified in some standards. IEC 61518 has been prepared by subcommittee 65B and I was one of the subcommittee members. I am really surprised that DIN 19213 is still used after all these years, although there is no technical reason to specify this obsolete standard.

The difference between valves acc. to ISO 15848 & bellow-sealed valves

The difference between valves acc. to ISO 15848 & bellows-sealed valves.

Diminishing natural resources and expanding energy use are forcing the industry to regroup. The growing stringency of legal requirements obliges companies to use emission-reducing equipment.

Eliminate leaks and overpressure

Mini valves are located at both ends of the sampling cylinder. They have a shut-off function and prevent a leakage of the medium. Rupture disc holders provide protection against overpressure in the sampling cylinder. Learn more about mini valves and rupture disc holders.
