IMI’s Air-Spring Operated Steam Generator Blowdown Isolation Valve ensures containment integrity in nuclear power plants. Designed for continuous operation, it handles particulate-laden flow streams while providing tight shut-off in safety-critical scenarios. The air-to-open actuator eliminates solenoid valve failure risks, while a Y-pattern globe body minimises capacity losses. Quick-change trim enables easy maintenance, and high-force actuation ensures compliance with MSS-SP-61 shut-off standards. Constructed with stainless steel actuator components, this valve is fully ASME Section III, Safety Class 2, and Seismic Category I qualified. Its robust design ensures long-term performance in demanding nuclear applications.
