DMBC

The BYVAP desuperheater steam device type DMBC is designed for accurate and economical control of steam temperature. The DMBC is a complete temperature control valve, which cools overheated steam by introducing water into the steam stream thanks to a high efficiency multi nozzle design.

This desuperheater can rely on simple operation and excellent spraying from high-quality nozzles, which greatly reduce the risk of water accumulation in the pipe and large turndown ratio.

The DMBC shall be designed:

  • to have a metal/metal class V between the starry seat and the plug
    without gaskets or springs,
  • to be installed vertically or horizontally, if the actuator is properly supported
  • with high specification Vortex nozzles welded in place,
  • with a driven plug with low friction segments,
  • with high-strength stainless steel spray head
  • class 1500
