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.
