Over 50 years' experience and success in valve constructionLOHSE 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. 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.

FSM Frankenberger GmbH & Co. KG
The specialists for clean water with 30 years experience
FSM was established in Pohlheim in 1970. During the first years'activities, manufacture of cooling water installations provided the entry into the environment engineering sector. Coarse bar screens and scrapers were the main products in the first phase. The increasing demand and new requirements for environment friendly products caused us to concentrate on sewage engineering.
Development work on new and existing designs enabled us to make continual improvements to our installation components and units. Our product range was extended to meet the changing conditions and new problems encountered in practice.
As a result of increasing demand for our products, we have expanded to become a medium size company. In the early nineteen nineties we opened a second factory at our subsidiary in Walow, Mecklenburg-Vorpommern.
Today we are able to offer a comprehensive range of equipment for sewage plants which have won a large selection of satisfied customers at home and abroad.
Our products are characterized by robust construction and reliable performance. Our sales engineering department boasts a qualified team of engineers who are available to deal with inquiries and propose solutions to customer problems.
Bearing in mind the increasing complexity of innovative solutions, FSM with its high standards of quality is well placed to take on cooperation projects at home and abroad.
