Steam Pressure Reducing Valves

Importance of Pressure Reduction:

  • Steam boilers are usually designed to work at high pressures. Working them at lower pressures can result in carry over of water.
  • Steam at high pressure has a lower specific volume which means that a greater weight can be carried by a pipe of a given size.  We recommend distribution of steam at high pressure and reduction at the point of usage. This reduces capital loss for piping and insulation and also reduces distribution losses.
  • Steam pressure may be reduced to save energy. Steam at lower pressures has higher latent heat. Reduced pressure of steam also leads to reduced heat loss and lower flash steam formation from open vents etc.
  • Since the pressure and temperature of steam are related, controlling the pressure enables us to control the temperature in the heating process.
  • Pressures must be reduced so that they are within the rated safety limits.
  • In plants where steam usage takes place at many different pressures, pressure reduction allows generation of steam at a single high pressure and subsequent reduction to the desired pressure at the point of usage.
