Title: Gunther Dornhoff: Innovator in High-Pressure Valve Technology
Introduction
Gunther Dornhoff is a notable inventor based in Hagen-Emst, Germany. He has made significant contributions to the field of chemical engineering, particularly in the design of valves for high-pressure applications. His innovative approach has led to the development of a unique valve that addresses the challenges faced in tubular chemical reactors.
Latest Patents
Dornhoff holds a patent for a three-way valve designed for use with tubular chemical reactors operating at pressures exceeding 1000 bar and temperatures above 250 degrees Celsius. The patent details a valve construction where the wall thickness of the lower valve part in the inlet/outlet duct area is at least 35% less than that of adjacent wall areas. This undersize is compensated by the prestress applied by the tightening bolts of the upper valve part. Additionally, a lens-type seal is incorporated between the lower and upper valve parts, which not only seals the connection but also serves as the valve seat. Notably, the thermal conductivity of the seal is at least 50% lower than that of the valve material, enhancing the valve's performance in extreme conditions.
