9907-1106 CPC-II 10 bar, Zone 2, simplex, Enhanced Dynamic Version (current-Pressure Converter, second generation) is an electro-hydraulic pressure regulating valve controller designed to position single-acting steam turbine valve servos. With excellent accuracy and resolution, the CPC is ideal for turbine valve control and associated turbine speed and load control.
The second generation current-pressure converter (CPC-II) of the Woodward 9907-1106, 10 bar, 2-zone, simo version 9907-1106n with enhanced dynamic performance, is an electro-hydraulic pressure regulation control valve for positioning single-acting steam turbine valve servers/actuators. CPC-II addresses one of the industry's number one reliability issues, oil contamination affecting equipment uptime and performance.
The CPC-II 9707-1106 accepts pressure demand signals from 4-20 mA and precisely controls the oil pressure to precisely position the single-acting steam turbine governing valve. Accurate and stable steam valve control is directly related to the improvement of steam turbine speed and load control and the reduction of mechanical wear of the system.
