VOITH DSG-B05243 (TCR91868300) I/H Electro-Hydraulic Converter

Product Description

The VOITH DSG-B05243 is an electro-hydraulic I/H converter (current to hydraulic pressure converter) for Voith turbine governing systems. It converts standard 4–20mA electric control signal from turbine controller into proportional hydraulic output pressure, to drive hydraulic actuator and steam/gas control valve. TCR91868300 is the factory drawing / serial reference number for this unit. It is widely used for steam turbine speed governing and load control, a core spare part for Voith turbine control hydraulic loop.

FAQ

Q: What is the difference between DSG-B05243 and DSG-B05242?
A: They belong to the same B05 0–5bar series; suffix difference is defined by internal coil, zero/span adjustment and explosion-proof configuration.

Q: Can it be replaced by DSM series converter?
A: DSM is the newer upgraded series; it can be used for system upgrade, but piping, signal calibration and mounting bracket need modification.

Q: What maintenance is required for DSG-B05243?
A: Regular oil filtration, zero & span calibration, seal inspection; overhaul includes coil test, spool cleaning and seal kit replacement.
