In severe services of high temperature and high differential pressure, the patented KOSO VeCTor multi-stage trim gives accurate control and long life, free from cavitation erosion and noise, on compressible or incompressible fluids.
Its performance and durability reduce maintenance costs and simplify the system, as diffusers and silencers are no longer required. The 500M (up to level 24), 500D (disk stack, up to level 40) and 500J (up to level 8) models are selected according to fluid conditions and budget.
Key features
- Labyrinth disk stack trim limits fluid velocity at every stage
- Eliminates cavitation, flashing damage, erosion and noise at the source
- No need for downstream silencers or diffusers
- Up to 40 pressure reduction levels
- Globe or angle bodies, integral flanged or butt weld ends
- Pneumatic, electric or REXA electro-hydraulic actuation
