Currently V-ball vendors, domestic valve industry research and development capabilities are still weak, the basic experience of staying in approach designed V-ball manufacturers, product development can only be digested and absorbed some foreign reference design information and samples, the true sense The new product developed 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 this ball valve are fixed, but also single-seat sealing valve, regulating valve in the best performance of Shandong valve is equal percentage flow characteristic, adjustable ratio of 100: 1. It has a shearing action between the V-notch and metal seat, especially for fiber-containing tiny solid particles, slurry and other media. It has the same ball rotated 90 degrees operation, except that the cock body is a sphere, a circular through-hole or channel through its axis.
