Since the 1970’s Circle Seal has been providing instrumentation valves to the nuclear power industry. Ranging in sizes from ¼” to 1” these valves are typically installed in Safety-Related and ASME Code Section III installations.

Instrumentation Valves

To ensure that the nuclear industry would continue to receive support for Circle Seal products, Curtiss-Wright Nuclear and Circle Seal formed an exclusive partnership. Through this partnership, Curtiss-Wright Nuclear has been approved to manufacture Circle Seal Safety-Related and ASME Code Section III valves under its Appendix B program and ASME N and NPT Stamps.
