Schroedahl Type DKT Steam-Atomizing Desuperheater

Schroedahl Type DKT Steam-Atomizing Desuperheater

Schroedahl Type DU Pressure Reducing Valve with Integrated Atomizing Steam Cooling for Heavy Steam Conversion Applications

Product Features

  • Particularly large power range thanks to integrated motive steam cooling system for perfect cooling
  • For optimum handling of diffi cult operating conditions, high-quality temperature control and optimum protection against temperature shocks (valve and piping)
  • Low-noise, multi-stage design of the throttle body (perforated bushing)
  • Screwed cover or self-sealing design
  • High quality multi-level perforated bushing design for pressure control and quiet operation
  • Special solutions for installation in existing systems possible

Applications

  • Steam conversion for high pressure and high temperature reduction, e.g. high pressure to low pressure bypass stations and for process steam conversion

Nominal diameter: DN 25-1200 / NPS 1-48

Pressure Class: PN 40-640 / Class 150-2500

Function

SCHROEDAHL belongs to the internationally leading suppliers of innovative, modern steam converting technology.

Our intensive development work means that we are always able to overcome barriers and implement new, ground breaking solutions in the fields of steam conversion valves and steam cooling in the interest of our customers. In addition, we develop our own mathematical models through a sophisticated engineering, analyse different loads and stresses and detect potential weak spots.

For the manufacturing, we have an extensive amount of CNC-machines. Based on our considerable material know-how, we use selective material characteristics and construct high-quality welding connections.

Thus, we are able consistently to expand the limits of what is technically possible. Even within the scope of extremely challenging, highly complex processes and tasks, we will find the technically appropriate solution.

We were, for instance, the first supplier to develop a steam converting valve with a nominal size of just one inch. We have exceeded the temperature range limit of 560° C/1040° F. Some of the SCHROEDAHL products can also resist a pressure of up to 500 bar/7250 psi.
