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.
