WOODWARD 9907-1349｜Current Pressure Converter｜

Core positioning: Used for precise control of oil pressure in the servo mechanism of single acting control valves for steam turbines, receiving 4-20 mA commands and converting them into stable oil pressure to achieve closed-loop control of valve opening, speed, and load; Suitable for the hydraulic source of turbine lubricating oil, with anti pollution and fault safety characteristics, it is the core spare part of the turbine control system.
Core functions: redundant input voting, precise pressure control, valve linearization compensation, fault self diagnosis, safe oil return, anti pollution self-cleaning
Typical applications: Control of steam turbine inlet valve, extraction valve, bypass valve, speed/load closed-loop regulation, safety protection system
Manual operation: Built in manual travel screw, local/remote manual adjustment of oil pressure (with safety logic)
Reliability: Long MTBF, suitable for continuous operation of steam turbines
Installation method: Install in any posture, with a 4 × M10 deep 23mm threaded hole at the front of the hydraulic end
Size (approximately) 290 × 270 × 270 mm
