Masoneilan 49000 Series

V-LOG™ Low-Noise Anti-Cavitation Valve

49000 Series V-LOG valve has an enlarged body gallery and up to 36 stages of pressure reduction via stacked disk trim. It handles severe high-pressure drop applications with gas expansion, noise, and cavitation control. The cast globe body is lighter and smaller than forged bodies, reducing installation costs, and V-LOG trim suits compressible and incompressible fluids.

The V-LOG Trim

can be configured for use with either compressible or incompressible fluids under severe service conditions making the 49000 Series valve a superior choice for liquid and gas applications including:

  • Boiler feed water start-up and control 
  • Steam letdown
  • Pump discharge 
  • Water reinjection
  • Gas recycle
