Product Description
Product Overview
The Woodward 9907-1200 is a second-generation Current-to-Pressure Converter (CPC-II) designed for precise control of steam turbine valve servos in industrial applications. This electrohydraulic pressure-regulating valve control accepts a 4-20 mA demand signal and converts it to an accurate oil pressure output to position single-acting turbine valve actuators. Rated for 10 bar operation in Zone 2 hazardous locations with a simplex configuration and enhanced dynamics, it is ideal for turbine speed and load control in power generation, oil & gas, and industrial processing environments.
