Automatic Recirculation Valve

It is also known As ARV, it’s a multi-function valve whose initial function is to ensure the pre-determined minimum flow through a centrifugal pipe all the time. It plays a vital role here as centrifugal pumps suffer from heating problems and if ARV is not available it can permanently damage the pipe of it dry out.

ARV application In Industry:

The Automatic recirculation Valves are ideal designs for the purpose of protecting pumps. They come in ahuge variety and are found In most industries.

  • General centrifugal pumps
  • Cooling plant feed pumps
  • Process liquid pumps
  • Boiler feed pump
  • Crude of Pumps
  • Fluid gas pumps for LNG,LPG, etc
  • Boosters pump
  • Seawater injection pumps
  • Firefighter pumps

Features of Automatic Recirculation valve:

  • Modular design
  • Automatic bypass operations
  • Nonreturn function
  • Pressure moderation
  • Bore which cleans itself
  • Customized pressure control

ARV operating conditions

There are three main conditions in order of working of an ARV.

-Main flow only, bypass closed
-the combined flow
-No main flow, only bypass
