Series 418

Our highly corrosion-resistant overflow valve in a closed, gas-tight design offers maximum flexibility and efficiency for use in demanding environments. Thanks to the various sealing options, the overflow valve is suitable for a wide range of compressible and incompressible media, including gases, liquids and aggressive chemicals. With its wide pressure ranges, it enables precise pressure regulation and is ideal for applications where overflow valves for different pressure ranges and applications have to be kept in stock.

The overflow valve is characterised by maximum ease of maintenance. The integrated, replaceable valve cartridge enables easy maintenance and saves time during servicing. Adjustments or settings can be made without difficulty, even during operation, which makes it particularly efficient for use in continuous processes.

Discover the advantages of our overflow valves, which impress with high corrosion resistance, flexible application options and easy maintenance – ideal for industrial applications where reliability and versatility are crucial.
