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 blast furnace gas to allow maintenance on the turbine. The inlet shut-off valve is used to positively isolate the TRT line from BFG main line during the TRT down time periods.

TRT (Top-pressure Recovery Turbine)설비는 제선공정에서 발생된 Blast Furnace Gas로 발전 터빈을 구동하는 설비이며 주요 배관에 설치되는 밸브입니다.
완벽한 씰링을 요하는 가스배관에 사용하기위하여 설계된 밸브입니다. 개폐시 BODY SEAT가 CLAMP / UNCLAMP 동작과 DISC가 슬라이딩되어 구동이되며, 개폐시 BODY SEAT가 CLAMP / UNCLAMP 동작과 DISC가 슬라이딩되어 구동이되며, SEAT내구성이 다른밸브보다 월등히 뛰어납니다.
