CPC-II
The Woodward CPC-II (current to pressure converter, generation II) is an electrohydraulic pressure-regulating valve control designed for use in positioning single-acting steam turbine valve servos. This CPC's superb accuracy and resolution make it ideal for steam turbine valve control and related turbine speed and load control. The Woodward CPC accepts a 4-20 mA pressure demand signal and accurately controls oil pressure to precisely position single-acting steam turbine governor-valves. Precise and stable steam valve control directly relates to improved steam turbine speed and load control and reduced system mechanical wear.
