Distillation technology
For crude oil, also with low abrasive components, we recommend our double-seat valves DN 50 - 400 PN 40 and DN 40 - 250 PN 160 (series 250, 280) as well as exclusively non-pressure-balanced versions of the series 8C, 6N, 6H in the nominal sizes DN 15 (1/2") - DN 700 (28") PN 40..160 (ANSI 150...1500) in distillation technology.
