The NozzleCheck is a non-slam check valve first developed in 1935. The first NozzleCheck valve installed in a nuclear power plant was in 1972; since then it has replaced over 800 conventional check valve designs.
In-Line Check Valves
Specifically designed to combat damaging transients and water hammering, the NozzleCheck valve has been improving systems in some of the most demanding nuclear plant applications.
With a number of designs, NozzleCheck offers check valves for large and small bore, dirty, high capacity, and severe service applications.
In 1992, Curtiss-Wright Nuclear started manufacturing NozzleCheck valves under its Appendix B Program. Since that time, Curtiss-Wright Nuclear has been exclusively offering ASME Section III Class 1, 2, and 3, Safety-Related and Commercial NozzleCheck valves to the nuclear industry.
