Pressure Reduction


Pressure Reduction 

According to the VGB guidelines, the pressure reduction of the sample water is carried out after the cooling. This prohibits for instance the separation of salts and, thus, guarantees a representative sampling. Special accessories for high demands in view of function and safety are available. Furthermore, the lifetime of the valves increases massively due to the reduction of the pressure only at a lower temperature. 


  • Pressure reduction up to 400 bar Simple and robust design as a needle valve 
  • Replaceable valve seat for abrasive media 
  • Differential threading for ease-of-use 
  • Setting of smallest sample flows through special angular form of the needle valve
