According to Wikipedia, Siemens AG is a German conglomerate based in Berlin & Munich. They are the largest manufacturing and electronics company in Europe with international offices.
One part of Siemens is known as SIEMENS COMBUSTION CONTROLS (often shortened to SCC). As one might gather from the name, this division is dedicated to products used in the industrial heating industry, and specifically, in control parts such as valves and flame safeguard controls and infrared flame detectors.
The Siemens Combustion Controls product line is useful for boilers, furnaces and industrial ovens from bread baking ovens to powder coating and kilns.
Siemens (SCC) can provide more than individual combustion components, but can pre-assemble them such as pairing an actuator to a VKG Butterfly valve.
