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.
