Woodward’s second generation current-to-pressure converters (CPC-II) 10 bar, Zone 2, 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.
Features:
Oil contamination resistant (ISO20/16)
Precise fluid pressure control
Stable & linear valve control
Included valve linearization table (Full range <0.2%)
Redundant inputs/sensors for critical applications
