DTP & DTP-SS Abv valves Velan Vietnam

Discrete Tortuous Path Valve for:

  • Choke application
  • Server control service
  • Turbine by Pass


Turbine Bypass

ABV Energy supplies complete de-superheated Systems for Turbine Bypass lines, formed by DTP SS CONTROL VALVE used to control pressure reducing and SPRAY WATER CONTROL VALVE having the function to de-superheat the steam.

The de-superheating section is located immediately downstream of the DTP Control Valve, allowing to preserve valve trim and main body from thermal shock phenomena.

All bypass systems are custom designed and engineered for each installation to suit the various turbine designs and operating regimes. This ensures that the bypass system is ideally matched to fully satisfy the required performance envelope.

The method of actuation also has to be carefully selected to meet the demands of the operating scenarios and failure modes. Normal actuation will be either hydraulic or pneumatic depending on the speed and accuracy that the plant operating characteristics demand.
