9907-1105 Woodward Electro-hydraulic converter CPCII current-pressure converter

Woodward’s second generation current-pressure Converter (CPC-II) 10 bar, 2-zone, simplex version, with enhanced dynamics, is an electro-hydraulic pressure regulation control valve for positioning single-acting steam turbine valve servos/actuators. CPC-II addresses one of the industry’s number one reliability issues where oil contamination affects equipment uptime and performance.

The CPC-II accepts the 4-20 mA pressure demand signal and precisely controls the oil pressure to precisely position the single-acting turbine regulating valve. The accurate and stable control of steam valve is directly related to the improvement of turbine speed and load control, and the reduction of system mechanical wear.
