Turbine Bypass Valve

The turbine bypass valve is an engineered assembly that takes main steam from a point near the turbine inlet and reduces its energy so that it can be directed into the air-cooled condenser. The pressure and temperature reduction is accomplished using a multi stage control valve with an integral desuperheater at the valve discharge. During startup and in load rejections where the turbine is taken out of service, use of this valve gives flexibility in how operators respond to turbine trips.
