Municipal sewage treatment

When LOHSE COMPACT-gate valves of acid resistant stainless steel are installed in waste water treatment plants, the need to use expensive isolation appliances to guard against contact-corrosion is removed.

Food industry

LOHSE COMPACT-gate valves are widely used as shut-off valves for viscous and glutionous media as for instance in salt works, sugar mills, wine making industry, breweries etc.
In special designs, the non-metallic components of the LOHSE valves can be equipped with FDA-approved components. The respective suitability must be checked for each application.



Stainless steel housing

  • of a rust and acid resistant material which prevents not only its own corrosion but also contact corrosion on stainless steel piping therefore saving expensive isolation materials
  • two parts – easy to maintain
  • made from pressed stainless steel plate which keeps its shape – light and easy to install
  • the frame for the drive acts at the same as a fastening for the switch and control mechanisms

Plastic slide lining

  • this material has the highest slide properties but at the same time is abrasion resistant
  • resistant to temperature extremes and acid
  • easy to change

Valve plate of stainless steel

  • of a rust and acid resistant material

Flow opening = the nominal width of the piping

  • no contraction caused by guide strips to the side
  • by using an elastomer you guaran-tee a completely smooth flow

Drives all part of the proven LOHSE modular system

  • easy-to-use handwheel with a handle grip to quickly open or shut the valve by hand
  • electro or pneumatic drives to enable activation from a distance
  • drives are exchangeable in the case of all our valves even in an assembled condition
  • drive accessories can be optimally attuned to one another
