Main Steam Isolation Valve

Application Scenario: The main steam isolation valve is an important safety equipment for Hualong I and CAP series nuclear power plants, installed in the main steam system of the second circuit. In the event of a main steam line rupture, the valve can be quickly closed within 5 seconds, effectively isolating and restricting the release of steam to ensure the safe operation of the nuclear power plant.
