Woodward 9907-1200 CPC-II Current to Pressure Converter

Description

The 9907-1200 CPC-II is an electrohydraulic pressure-regulating valve control designed for precise steam turbine valve control. It uses an accurate internal pressure sensor and a PID controller to regulate the positioning of single-acting steam turbine governor valves.

Features

• Pressure Control: Accepts a 4–20 mA pressure demand signal to accurately control oil pressure and position single-acting steam turbine governor valves.
• Redundancy: Configurable to accept redundant pressure demand inputs from one or two controllers.
• Failsafe Mechanism: Internal valve-return-spring forces the CPC to a failsafe position, ensuring safe closure of turbine control valves in the event of an internal unit failure.
• Robust Design: Features a strong actuator, corrosion-resistant materials, a single moving rotary valve, and a self-cleaning port design.
