Applications
Paper industry and chemical industry
LOHSE COMPACT-gate valves have proved their value and reliability in all branches of ins paper and chemical industries. CNA-valves are “shut-off” type valves. The type is suitable for shut-off of stock and aggressive media.
Industrial 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.
Special models
For special applications, we can supply special valves constructed of various materials for differing temperatures, pressures and sealing properties to suit the particular application.
Media
Construction
Housings entirely of stainless steel
- pressed steel design
- corrosion and acid resistant
- light
- easy to maintain
- the handwheel support also serves as a mounting for any switchgear or control apparatus
Slide guides of special plastic
- abrasion resistant
- excellent anti-friction properties
- temperature resistant
- acid resistant
- easily replaceable
Valve plate of stainless steel
- specially shaped to prevent depositing stock
- built in strength to resist water pressure vibration
Bore cross section = nominal diameter of piping
- blockage-free due to special slide plate and housing design
- no stringing of fibres is possible
Actuating elements in well-proved LOHSE modular system
- interchangeable on all valves of our make
- also interchangeable on the incorporated existing valve
- reduced stock holding
100 % water-tight
- seals resistant to temperature and acids
- seals easily replaceable but firmly anchored in the valve housing
