Nuclear Generation

Delivering the Nuclear Promise

ValvTechnologies provides our “Nuclear Promise” by addressing application obsolescence, along with improved personnel and equipment safety, lost megawatt recovery, reduced maintenance, spare parts, and service solutions for vent, drain, isolation, and check and control applications in nuclear generation.

By addressing application obsolescence, changing linear technology with quarter turn metal seated ball valves, the plant has also realized improved personnel safety, eliminating downstream piping degradation and improving equipment reliability. They have also reduced maintenance, spare parts, and service needs by addressing vent, drain, isolation, applications 3” and under in high energy nuclear applications with ValvTechnologies’ solutions.
