Accessories: Perforated Discs
  • Print

For applications with high differential pressure in case of gases or fluids,mounting of one or more perforated discs can reduce problems with sound pollution or cavitation substantially.


The pressure between Valve and silencer disk is increased due to the built up back pressure. This results in a reduced pressure drop inside the valve, which allows to avoid the evaporation pressure to fall below the critical value and therefore cavitation that could destroy the valve.
