Applications
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.

Construction
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
