The main features and advantages 1. Motivation from the media inside the valve, no external power source, when the pump stops when open, the valve can be run automatically in accordance with the laws of the pump action. No manual, electric, pneumatic and hydraulic and other external forces, not manually, with automatic slow opening, fast closing, slow closing effect, safe and reliable operation. 2. Big flowing area, the valve plate transverse cross-sectional area than the average pump control valve *0% of the running resistance, energy-saving effect, the valve resistance coefficient is 0.**0.8. 3. The valve plate is streamlined. When into the valve, if the fluid is laminar flow, the valve can make the fluid remained laminar, and thus applicable to certain conditions. 4. The conical sealing surface of valve and spherical sealing surface of valve plate are made of high-hard material which can be cut, crushed, arranged a variety of filamentous, granular suspension, semi-suspended impurities, are able to automatically center. Another feature of the eccentric spherical is that it can automatically compensate for wear, especially the wear of the ball-shaped depression. 5. The sealing area of overlap is small, taking full advantage of all the energy within the medium valve body to make valves seal .The sealing energy is giant, making zero by zero, and head-sealing smoothly achieved. 6. Its structure combines all advantages of three eccentric high valve seal butterfly valve, half-ball valve, wedge gate valve, and globe valve , and abandons all of their flaws. 7. Can be used for centrifugal, mixed flowing, as well as axial flowing pump. 8. Floor space is relatively small, especially suitable for large diameter pipeline (DN***0mm above). 9. with simple and reasonable structure , convenient to arrangement, long life span.
