Valve Co., Ltd. Shandong Everbright between the valve and seat are due to gap-free rotary V-ball manufacturers, so have a lot of shear force and self-cleaning properties, especially for the suspension containing fibrous or tiny solid particles and solid, particulate control. Therefore, this product can be widely used in petroleum, chemical, paper, power, metallurgy, pharmaceutical, environmental protection and other industrial sectors of the automatic control system. For a long time, study the hydraulic characteristics of the valve is almost entirely determined by experiment. By the large number of tests are summarized charts and empirical formula obtained data is the main basis for designers. As the valve wide range of real-time will be quite different in the same type of internal structure, and product updates quickly. Thus, according to data on the test results of products made in the past to design new products, often with a large error. This is a key factor regulating valve new product development.
