BI-DIRECTIONAL metal sealing rotary ball valve

The bidirectional metal sealed rotary ball valve is developed by combining the superior sealing performance of ball valves with the advantageous structural performance of butterfly valves. It not only has the advantages of bidirectional sealing and long service life of ball valves, but also has the advantages of small volume, adjustability, and light weight of butterfly valves. Its essence is a butterfly structure eccentric hemispherical valve.The sealing principle combines the front end sealing of the fixed ball valve with the forced sealing of the eccentric butterfly valve, thereby achieving bidirectional high and low pressure cut-off. Widely used in industrial circulating water systems, thermal pipeline systems, water supply and drainage pipelines, recycled water pipelines, water supply booster pump stations and other working conditions.

Product Features

1. Using mathematical models of fluid motion and 3D design software to create high-performance ball valves;

2. Capable of achieving bidirectional sealing and superior sealing performance;

3. The valve adopts the principle of eccentric wedge tightening, and the sealing surface adopts a metal spherical seal with shear scraping function, suitable for working conditions containing solid particles;

4. When opened, the valve disc is detached from the valve seat without any contact, the switch is lightweight, and the operating torque is small;

5. The structural length is the same as that of butterfly valves, making installation convenient and effectively reducing installation and maintenance costs;

6. Multiple wear-resistant materials are combined, and the valve materials are all hardened for longer service life;

7. The compressed version of the hemispherical valve can achieve high-pressure and large-diameter production.
