FLOWsafe overflow valves

For pressure protection or to ensure constant pressure retention in feed pipes

Your benefits

  • Flexibility: The variable 360° connectivity paired with the double spherical housing allows any custom piping design.
  • Hygienic Design: The one-piece double spherical housing allows very little spacing between the pipe levels. Minimised sealing area and optimised product space design for reliable cleanability and safe drainage.
  • Profitability: Valve inserts that can be full disassembled and easy to replace seat sealings allow for short and optimised servicing cycles.
  • Productivity: Back pressure-optimised design thanks to valve plunger with valve disc; back pressure thus has no influence on the function.
