Provides pressure reduction for applications which require more than a simple plate orifice.

The HBE MSO works by directing the fluid into a vortex flow and breaks down the pressure across several stages. The fluid passes through a multiple hole flow straightener upon exiting the orifice, which directs the fluid in a laminar direction downstream of the orifice. During pressure reduction the fluid is always above its vapor pressure, preventing destructive cavitation and flashing forces.

The MSO can be used for many high pressure reduction/small plow requirements. Specific examples include centrifugal pump minimum flow protection, warm up lines, strainer blow down, and control valve bypass.
