Feature

A TRT (Top-pressure recovery Turbine) is installed in the downstream of gas-cleaning equipment for a blast furnace.
The function of this valve is to provide isolation from BFG to allow maintenance on the TRT tuyrbine. The shut-off valve features a special water seal, which permit continued high tope pressure furnace operation, while the turbine is isolated. (Positive Isolation).

TRT (Top-pressure Recovery Turbine)설비는 제선공정에서 발생된 Blast Furnace Gas로 발전 터빈을 구동하는 설비이며 주요 배관에 설치되는 밸브입니다.
OSV는 TRT turbine설비의 정비시 후단부에서 흘러 들어오는 BFG GAS를 차단하여 안정적인 정비작업을 수행 할수 있습니다. 내부에 물이 공급되어 완벽한 가스 차단성능을 보유하고 있습니다. 설비에 따라 GOGGLE VALVE TYPE 을 사용할수 있습니다.
