Curtiss-Wright has partnered with Ringo Valves to provide the US nuclear power market with globe valves. Located in Zaragoza, Spain, Ringo valves has designed and manufactured their cast and forged valves for over 30 years. Their high QA standards, including ANSI and ASME, make them an international leader in the valve industry, and Ringo prides itself on only providing only the highest level of valve technology. Available in a variety of sizes, valve types, and materials, Ringo valves provide a wide range of solutions to any problem.
Globe valves are ideal for both on/off and throttling or control applications. Special globe valves serve more focused functions, like the choke design made for adjustability, the stop check design that is a combination of globe and check valves, or the bellows-seal design built for zero stem leakage. Curtiss-Wright provides Ringo's Choke, Stop Check, Bellows Seal, and Control globe valve designs for nuclear applications.
