Critical Applications



IMI NH valves can be found on applications on the nuclear side of PHWR, PWR, GCR and BWR nuclear reactor designs, where isolation of potentially lethal media is essential. Our valves are successfully working in Emergency Cooling Water systems, Primary Heat Transfer systems and Fuelling machines.


The high-performance valves have a robust design, with a service life of 40 years or more. As most applications are inside containment, they are manufactured in accordance with the ASME III Nuclear Code.
