Product description

The series orbital ball valve is a new type of pipeline valve developed and designed by our company with the introduction of foreign advanced technology. It is suitable for regulating, opening and closing pipeline fluids in natural gas, oil, chemical, metallurgy and other industries. Long-distance natural gas pipelines with hydrogen sulfide medium, many impurities and severe corrosion.

Features
1. The static single seat structure ensures tight, reliable, and zero leakage bi-directional sealing.
2. Top mounted design allows for online maintenance of the system.
3. The cam mechanism at the lower end of the valve stem can provide a mechanical wedge tightening force to ensure continuous tight sealing.
4. The opening and closing process is divided into two stages, with a short lifting stroke and easy operation.
5. During the opening and closing operation, the sealing surfaces are completely out of contact, without wear, with high operating torque and long service life.
6. The space formed between the ball and the valve seat during the rotation process increases the flow rate of the medium in the channel, thereby achieving the function of cleaning and sealing.
7. The fire resistance design of ball valves follows the provisions of standards such as API 607, API 6FA&JB/T 6899, etc. In the event of a fire that causes the soft sealing ring to burn, the fire resistant structure of the ball valve can prevent a large amount of medium leakage and prevent further expansion of the fire.
8. Valve driving devices include manual, worm gear and worm drive, and electric. Electric valves are easy to achieve automatic control, easy to operate, and safe and reliable.
