In the 24 years that I have been working in the field of industrial valves, I have dealt with many new requirements for the tightness of valves. Increasing energy consumption, dwindling natural resources and the ever-stricter legal requirements, forced the industry to rethink and use emission-reducing technology. This is also the case in the field of industrial valves. The requirements for environmentally friendly valves are also a recurring topic in the standardization committees in which I am a member, e.g., in the DIN specialist area of industrial valves, committee NA 003-01-01 AA Basic Standards.

In the 24 years that I have been working in the field of industrial valves, I have dealt with many new requirements for the tightness of valves. Increasing energy consumption, dwindling natural resources and the ever-stricter legal requirements, forced the industry to rethink and use emission-reducing technology. This is also the case in the field of industrial valves. The requirements for environmentally friendly valves are also a recurring topic in the standardization committees in which I am a member, e.g., in the DIN specialist area of industrial valves, committee NA 003-01-01 AA Basic Standards.
