Currently, the domestic valve industry research and development capabilities are still weak, the basic method to stay on experience in design, product development can only refer to some foreign design information and sample digestion and absorption of V-ball manufacturers, new products, in the true sense of self-development little work. The reason is the lack of design guidance and involvement of high-paying technology means new theory, but also a lack of performance parameters, temperature parameters of dynamic simulation tools and test equipment, less investment in basic research. V-ball works: By rotating the valve V-shaped opening to the valve flow or occlusion. V-ball open structure rigidity, hardness, high temperature, corrosion wide range of applications, economical and practical light torque. V-type valve closure member is a ball and the O-ball and plug valves of the same type. Configuration pneumatic actuators, electric valve positioner, air filter can achieve modulating valve V-ball price, V-Ball is a new valve is widely used in recent years. High-performance V-ball valve supplier light torque, high temperature, corrosion resistance, long life tough degree. Selection of metal seal seal Class VI level up. Dimensions include DN25 to DN500, pressure can be applied to all levels. V-ball vendors, Everbright valve manufacturer (certified), ball valves are provided by Shandong China Everbright Limited. Valve Co., Ltd. Shandong China Everbright (www.sdgdfm.com) Shandong Weifang, ball leader, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. Everbright valve leadership with the staff warmly welcome all inquiries negotiations to create a better future for China Everbright valve.
