  • ChannelStream trim prevents cavitation from forming and minimizes hydrodynamic noise even in the most challenging liquid applications. Staged pressure drops eliminate cavitation by maintaining pressure above the vapor pressure, never allowing cavitation to form.
    Cavitation Elimination Trim
  • DiamondBack trim prevents cavitation from forming and minimizes hydrodynamic noise even in the most challenging liquid applications. Staged pressure drops eliminate cavitation by maintaining pressure above the vapor pressure, never allowing cavitation to form.

    Dirty Media Cavitation Trim
  • Multi-Z valves are used if solids are entrained in the medium and if there is a possibility of cavitation forming. In addition this multiple stage valve is capable of reducing high-pressure differentials via a multiple stage relief process. Flowserve reduces pressure via division in partitions, a course which is different to that pursued by other suppliers. The major advantage is a noticeable reduction in wear combined with an extremely low-noise control valve. Likewise deviating from conventional procedures, in order to avoid cavitation a physically optimized technology has been implemented that achieves significantly better results.
