Overseas production of giant nuclear power industry valve highlights of the five
Foreign nuclear power valve comparison with the domestic nuclear power valve, valve full range of foreign nuclear power, advanced technology, excellent performance and high reliability. The United States in 1942 built the world's first experimental nuclear reactor, built in 1954, the former Soviet Union the world's first nuclear power plant. In the 60 years of nuclear power technology development, only in respect of nuclear power valve, the foreign form a complete design, test, manufacture, testing systems, has accumulated a wealth of experience, products mature, reliable technology. America's Westinghouse company, Canada's wieland company, Framatome of France and other Western nuclear power valve company holds contemporary advanced nuclear power technology. Whelan's nuclear power valves nearly 90% of the world's nuclear power plants have a good delivery record. The world's nuclear power plants in the nuclear island and conventional island in many important nuclear grade, non-nuclear grade valves, such as pilot-type safety valves, main steam isolation valves, control valves and other nuclear valve technology and markets are well-known nuclear power valve monopoly company, and the price is very expensive.
