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 spe ts 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.
This evolution began with valves made of cast iron and continued with valves lined with stainless through to today with valves made of corrosion and acid resistant stainless steel. The reject valves that were developed parallel to this and were conceived for the problem positions in waste paper processing, have since become the standard in recycling paper mills. We are now the only renowned manufacturer of knife gate valves with a service-friendly two-part housing. All others have long since abandoned this design because of manufacturing costs and now only have valve bodies with a one part housing. But the simplest way of replacing wearing parts is if the housing is in two parts. In addition, the one-part housing has the following further disadvantage: the space for inserting the valve plate in the housing has to be relatively large and this increases the danger of blocking and draining paper fibres. With our valve, this problem is prevented by the narrow tolerances between the valve plate and the smooth-running plastic internal shell. The valve guides are emptied via a specially shaped sturdy valve plate. A sophisticated system for attaching accessories and the drives - which are found here as the LOHSE modular system - is another advantage of our concept. Our repair service restores your used LOHSE COMPACT valve to an as-new condition with the guarantee of a new valve.
