Based on the mechanism of the metal hard-seal triple eccentric butterfly valve, our company has developed a bi-directional hard-seal rotary ball valve through improvements. This rotary ball valve is widely used in pump outlets, pipeline networks, recycling systems, elevated water tanks, flood-prone sewage systems, and backflow prevention systems, among others.

Product Features:

1. Bi-directional Shut-off Function: Bi-directional sealing, allowing the valve to be installed without regard to the direction of fluid flow.
2. Self-sealing Structure: The valve achieves reliable sealing under medium pressure.
3. High Sealing Specific Pressure: When the valve is installed against the fluid flow direction, the pressure medium acts on the valve seat, with the contact area being annular, resulting in a strong sealing specific pressure.
4. Wear Compensation Function: The valve has a long service life due to its ability to compensate for wear.
5. Unique Rotating Structure and Self-cleaning Function: The sealing surfaces of the valve disc and seat are spherical against conical, crushing solid particles during valve operation, providing a self-cleaning function.
