The control valve is driven by a servo valve actuator and hydraulic oil to drive the valve. Valve turbines consist of 4 types, namely Main Steam Valve, Governor, Reheat Steam Valve, and Interceptor Control Valve. MSV is a valve that opens and closes the main steam into the turbine HP, the governor works after the valve transfer from MSV functions to control the main steam flow rate, the RSV is a valve that opens and closes steam flow reheat money into the turbine IP, ICV acts like MSV which regulates the flow of steam in the reheat at the IP turbine. Effect of ICV valve opening reduction on turbine performance, when the ICV is open 100% turbine efficiency is obtained 40,105% (with a load of 295 MW) when there is a decrease in the ICV valve is only open 93% obtained turbine efficiency 37,984% (with a load of 295 MW)} }
