Main Steam Isolation Valve
We succeeded in domestic production of this valve through technical partnership with The Weir Group PLC. A main steam isolation valve isolates the main steam line when the unexpected occurs in a nuclear reactor operation, and is the key defensive system in a BWR nuclear power plant. As the only Japanese manufacturer of this valve, we supply to all Japan-made commercial BWR plants of major contract partners nationwide. Our valve products demonstrate their true worth in fields that demand constant, top quality sealing, and our valves for nuclear plants particularly boast exclusive experience in the nation.
