Control technology in a magnetic field

A project in a relating plant required control valves that could be used in a strong magnetic field. To meet this specific challenge, Velan relied on long-term partner Siemens. With a Siemens positioner with external electronics, the technical solution passes the qualification and function test in the magnetic field of 100 milliTesla (mT =unit of measurement for magnetic flux density) and meets the end customer’s strict requirements.

Velan gets supplied by similar industries such as the OEM (Original Equipment Manufacturer) department of Siemens Process Instrumentation. It therefore makes sense for the two companies to work together on the development of new innovative valves. This has led to an equal partnership, which is producing valve solutions that meet for example even the strict requirements in terms of vacuum density (helium leakage test) specified by the XFEL (X-Ray Free-Electron Laser Facility) in Hamburg, Germany. In the concrete project, the values also had to pass the function test in the magnetic field – which is a challenge even for proven Siemens Sipart PS2 positioners.
