Description:
The 9907-1200 is a CPC-II type current-to-pressure converter. Designed for precise control of single-acting steam turbine valve servo mechanisms/actuators, it accurately and reliably converts electrical signals into hydraulic signals. By receiving a 4-20mA current setting input, it provides a precise and stable hydraulic pressure output proportional to the input current, thus enabling precise control of valve position. This function is crucial for maintaining accurate turbine speed and load control, ensuring stable and efficient turbine operation in industrial environments. This device is particularly suitable for applications requiring high precision and dynamic response.
It not only solves the industry's primary problem affecting equipment uptime and performance—oil contamination—but also possesses numerous advanced features, including oil contamination resistance (compliant with ISO 20/16 standards), precise fluid pressure control, and stable linear valve control.
Features:
- Enhanced Dynamic Performance
Provides superior performance and responsiveness for harsh applications.
- Accuracy and Resolution
Enables precise control of valve positioning.
- Reliability
Designed for harsh industrial environments, providing long-term, stable service.
- Compatibility
Compatible with various turbine valve servo systems.
- Pressure Control
Receives pressure demand signals from 4-20 mA to precisely control oil pressure and position single-acting turbine speed control valves.
- Redundancy
Configurable to receive redundant pressure demand inputs from one or two controllers.
- Fail-Safe Mechanism
An internal valve return spring forces the CPC to a fail-safe position, ensuring safe closure of the turbine control valve in the event of an internal unit failure.
- Rugged and Durable Design
Features a high-strength actuator, corrosion-resistant materials, a single rotary valve, and a self-cleaning port design.
- Advanced Diagnostics
Provides real-time monitoring and diagnostic tools for efficient troubleshooting.
