Woodward CPC-DX Redundant Skid Mounted Current Pressure Converter
The CPC-DX 10 bar, 2 zone, redundant, has an enhanced dynamic dual transmission current-to-pressure converter skid for on-line (automatic and manual switching) service capability for uninterrupted operation to position single acting turbine valve servos in critical applications.
Features and Functions
Woodward’s redundant skid-mounted current-to-pressure converter (CPC-DX) is an electro-hydraulic pressure-regulating control valve for positioning single-acting steam turbine valve servos/actuators.
The redundant version of the CPC-DX accepts a 4-20 mA pressure demand signal and accurately controls oil pressure to precisely position the single-acting steam turbine speed control valve.
Accurate and stable steam valve control is directly related to increased steam turbine speed and load control and reduced mechanical wear on the system.
The integrated design of the CPC-DX redundant version allows for the cost-effective purchase and installation of a hydraulic assembly that provides all the isolation and support benefits of a fully segmented current-to-pressure converter.
