MARTIN LOHSE GmbH Over 40 years' experience and success in valve construction LOHSE Knife Gate Valves for the Paper and Chemical Industry Long before the actual start of our valve development and production programme in 1962, we were already partners of the paper industry. As manufacturers of pulp vats, containers and machine parts our specialists were always present when it was a matter of solving problems at our customers. It was therefore a logical step that we also addressed the problems of valve technology handling pulp and fibre. The complete development of our knife gate valves rests always on close coordination with the experts from paper and paper machine manufacturers.
