Abstract

The double seat valve includes a hollow rod (6a) with a second valve housing part (1b) in the passage region to act as a pressure equalizing piston (6b). Its cross section is roughly the same as the through passage cross section (AN) between the valve housing parts (1a, 1b). The hollow rod is reduced to the minimum cross section for the necessary strength in the region between the second closing part (6) and the pressure equalizing piston.
