V-ball for the overlapping continuous reforming catalyst device to control the flow path in the flow of solid particles, while three valve isolation system as part of V-ball model, a total of four full-device, installed in the regenerated catalyst and to be born vertical pipe flow through the catalyst. This valve combines the effectiveness of ball valves and angle valves firmly together, shearing action between the open V-shaped notch in the ball and the ball sealing contributed to a smooth non-blocking operation, particularly applicable to solid materials. The valve body is 316SS, surfacing Stellite alloy, sealed for Stellite hard seal with the seal protector ring and the corresponding V-sealing valve springs can be used to adjust the thickness shim V-ball valve located and a V-center gap between the ball and the metal seal remains within a certain range, such a structure can greatly reduce the catalyst and the valve, valve seat wear, valve inch chopped off to prevent the catalyst, while making the maximum forward and reverse allowable leakage rate is maintained at the required level to meet the N, gas isolation requirements. This valve V-ball valves are fixed ball Weifang, is also a single seal valve seat, adjustable valve in the best performance, 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. Weifang valve _ Everbright valve manufacturer (certified) _V type ball valve 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.
