Applications
Paper industry
LOHSE stock valves with through-going slide plate have been successfully tested thousands of times in all areas of the pulp and paper industry. Valve types CDS and CDSV are installed of shut-off valves for pulp with a high degree of contamination, owing to their absolutely smooth, pocket-free passage.
Chemical industry and food industry
LOHSE stock valves with through-going slide plate , in special design with food-grade components, are used as shut-off valves and regulating valves for viscous, pulverulant, granular and sticky substances.
Waste treatment plants
LOHSE stock valves with through-going slide plate can be found in waste treatment plants for the shutting off of viscous and aggressive substances.
Special valves
On request we can supply specially designed valves of the most varied materials (e. g. titan) for special fields of application.
Media
Construction
Housing entirely of stainless steel
- corrosion and acid resistant
- easy to maintain
- the handwheel support also serves as a mounting for any control apparatus and protection guard
Slide cups of special plastic
- abrasion resistant
- excellent anti-friction properties
- temperature resistant
- acid resistant
- easily replaceable
Valve plate of stainless steel
- corrosion and acid resistant – type CDSV has a hardened valve plate
- bare cross section = nominal diameter of piping
- no stringing of fibres is possible
- free of dead space in open position
100 % water-tight in both directions
- seals resistant to temperature and acids
- seals easily replaceable but firmly anchored in the valve housing
Actuating elements in well-proved LOHSE modular system
- interchangeable an all valves of our make
- also interchangeable on the incorporated existing valve
- reduced stock holding
