Hermetic valves

ИА01017М, ИА01018М

Are constructed for installation at NPP as shut-off devices on air ducting of ventilation systems as well as facilities of storage and recycling of radioactive wastes. Valves can be used in systems that are important for safety including systems of normal operation and safety systems that are installed at NPP with VVER–1000, VVER–1200 and in hermetic boxes of NPP with VVER–440 and in hermetic boxes RBMK.
