The WOODWARD 9907-1254 is not a mechanical actuator. Instead, it is specifically identified as a CPC-II – Voith E360 Adapter Manifold.
WOODWARD 9907-1254: CPC-II – Voith E360 Adapter Manifold
The WOODWARD 9907-1254 is a specialized accessory for Woodward’s CPC-II Current-to-Pressure Converters. Its primary function is to facilitate the upgrade or replacement of a Voith E360 I/H (Current-to-Hydraulic) Converter with a newer Woodward CPC-II unit, ensuring seamless mechanical and hydraulic integration.
Product Overview
This part number designates a specific manifold designed by Woodward to simplify retrofits. Instead of being an active control device itself, it serves as an interface or adapter plate that allows a CPC-II to physically and hydraulically connect into a system previously configured for a Voith E360 I/H.
- Product Type: Adapter Manifold / Upgrade Kit Component
- Manufacturer: Woodward
- Part Number: 9907-1254
- Model Designation: CPC-II – Voith E360 Adapter Manifold
- Function: Provides the necessary mounting and hydraulic connections to install a Woodward CPC-II Current-to-Pressure Converter in place of a legacy Voith E360 I/H unit, without requiring significant modifications to the existing hydraulic piping or mounting arrangements.
- Benefit: Simplifies and speeds up the upgrade process, reducing downtime and installation complexity when replacing older Voith units with Woodward’s advanced CPC-II technology.
Detailed Product Description
The Woodward 9907-1254 is part of Woodward’s strategy to provide easy upgrade paths for their customers. The CPC-II (Current-to-Pressure Converter, Generation II) is a highly accurate and robust electrohydraulic pressure-regulating valve control that translates a 4-20 mA electrical signal into a precise hydraulic pressure to position steam turbine governor valves. The adapter manifold ensures that this superior control can be implemented efficiently.
- Mechanical Compatibility: The manifold’s design ensures that the mounting footprint and porting align with what would be expected for a Voith E360 I/H, allowing the CPC-II to bolt directly into the existing space.
- Hydraulic Integration: It provides the necessary hydraulic passages to route supply oil to and from the CPC-II, connecting it correctly to the turbine’s hydraulic system (e.g., to the single-acting servo of a turbine valve).
- “Dirt Buster” Technology of CPC-II: While the manifold itself doesn’t possess this, it enables the integration of CPC-II units which are known for their “Dirt Buster” technology. This refers to a robust design that allows the CPC-II to operate reliably even with contaminated oil, a common issue in older hydraulic systems. Upgrading to a CPC-II via this manifold helps mitigate oil contamination-related issues.
- Enhanced Dynamics and Redundancy: By facilitating the use of a CPC-II, this manifold allows users to benefit from the CPC-II’s enhanced dynamic response and redundancy capabilities (e.g., accepting redundant pressure demand inputs and internal health monitoring), improving overall turbine control system reliability and performance.

Typical Applications
The WOODWARD 9907-1254 CPC-II – Voith E360 Adapter Manifold is specifically used in contexts where:
- Legacy Voith E360 I/H Converters are Being Replaced: It’s a key component in modernization projects for steam turbines that currently use Voith E360 I/H units.
- Turbine Control System Upgrades: Part of a larger effort to upgrade an entire turbine control system (e.g., moving from older hydraulic controls to modern electronic control with precise electrohydraulic interfacing).
- Enhanced Reliability and Performance are Desired: By enabling the installation of a CPC-II, it contributes to improved control accuracy, responsiveness, and resilience to hydraulic oil contamination.
