High temperature high pressure nuclear valve is our core product.We research and produce Nuclear 1 2 3 level gate valve,globe valve, check valve, regulating valve, safety valve, etc. for ship and power station. In 2011, we got ASME NUCLEAR 1.2.3 VALVE DESIGN AND MANUFACTURE CERTIFICATE AND STAMPING(N, NPT STAMPING), and now we are researching and producing blasting safety valves. Blasting safety valve Making use of Military blasting valve development results, combined with the introduction of the U.S. Westinghouse AP1000 blast valve technology, we developed a series of blasting safety valve, the technology has reached the international advanced level. 1.Using gunpowder to promote the drive mode, only a DC24V start signal can generat giant driving force to achieve the function of safety relief 2.Independent research and development of the blasting unit, control accuracy, security and high reliability 3.The key components of the valve body, piston, shear cap, connecting bolts are under strict production, processing and inspection process, in order to ensure product quality Operative standard We could produce as customers’ requirements, using ASME, GB standard.
