FEATURES & FUNCTIONALITY
Woodward’s second generation current-to-pressure converters (CPC-II) 25 bar, Zone 1, simplex version with enhanced dynamics are electrohydraulic pressure regulating control valves used to position single-acting steam turbine valve servos/actuators. The CPC-II solves one of the industries number one reliability issue of oil contamination affecting equipment uptime and performance.
The CPC-II accepts 4-20 mA pressure demand signals 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.
