Woodward 9907-018 Key features
Dual-mode control function: supports two speed control modes, Droop and Isochronous, suitable for parallel and stand-alone applications;
High-precision adjustment capability: PID closed-loop control system, speed stability can reach ±0.25%;
Adjustable start-up fuel limit: ensures that the fuel supply is controlled during the equipment startup phase to avoid speed shock;
Easy installation: standard panel installation, easy to quickly replace or integrate;
No communication dependence: independent analog control structure, strong anti-interference, suitable for remote unmanned sites.


Typical cooperation cases
North American shale gas processing plant: In a shale gas liquefaction project in Texas, the Woodward 9907-018 is used to control the feed valve of the high-pressure separator. Its 180N thrust ensures the rapid response of the valve in high-pressure and high-sulfur medium environments, and the annual maintenance times are reduced by 40% compared with similar products.
European refinery catalytic cracking unit: In the flue gas valve of the regenerator of an Italian refinery, the Woodward 9907-018 is combined with the Siemens PCS7 system to achieve pressure balance control between the regenerator and the reactor. Its IP65 protection and fluororubber seals successfully resist the erosion of catalyst dust, and there has been no seal leakage in continuous operation for 3 years.
Middle East desalination plant: In the reverse osmosis membrane inlet valve of the Jubail Phase II desalination project in Saudi Arabia, the Woodward 9907-018 is integrated with the AB ControlLogix DCS to accurately adjust the water inlet pressure. It has been operating stably for more than 20,000 hours in a high humidity and high salinity environment, becoming a benchmark for "zero failure" actuators in the project.
