High flow rates at low differential pressures. Can be adjusted and set externally during operation, for liquid and gaseous media, service friendly due to replacement cartridge. This overflow valve made of high-alloyed stainless steel combines all of these advantages.

According to the sealing- and diaphragm materials employed, these valves can be used for neutral and non-neutral media.

  • Flange connection
  • process equipment construction
  • Laboratory equipment
  • Pressure systems

For the protection of pumps against overload in closed circuits for neutral / non-neutral, non-sticky liquids
