The water in the boiler contains salts, which are generated due to the continuous evaporation. If these salts are not eliminated, when the density of the water increases, bubbles and foam are formed. These modified salts produce impurities which form sludge and encrusted deposits which adhere to the sides or the bottom of the boiler and to the smoke and flame tubes, together with particles of dirt, remains of electrodes, carbonic acid, oxygen, etc.
This leads to a high level of rust which may:

  • Destroy the metal plate of the boiler, causing high maintenance costs.
  • Produce thermal stress, causing cracks in the metal plate and weld seams.
  • Notably slow down heat transfer, which turns on an unnecessary and excessive fuel consumption

Therefore, the water supply must be suitably treated before it goes into the boiler.
For what purpose? In order to eliminate the corrosive elements that could be present and which eventually damage the boiler and affect the steam quality.
How? With our blowdown valve for bleeding dirt and sludge for steam boilers, model 460.
Splitting of model 460 in ANSI version (300lb)

The VYC industrial blowdown valve for bleeding dirt and sludge for steam boilers, model 460, was recently split. So far, it was manufactured in accordance with European regulations (EN). However, as of yet, this valve can be requested with ANSI300 Ib connections. As usual, we adapt our products to the demands of the market.
