Highlight: Side entry eccentric hemispherical valve
Product introduction:
The eccentric half-ball valve is a common spherical valve in which the contact between the hemispherical disc and the seat is
different from that of the straight-through half-ball valve or the rotary ball valve. In the eccentric half-ball valve, the center line
of the hemispherical disc is not aligned with the center line of the seat, so as to achieve precise regulation and control. It
drives the eccentric half-ball to rotate through the rotation of a worm gear (or electric) mechanism, thus realizing the opening
and closing of the valve. It has the advantages of small flow resistance, reliable sealing and stable performance, and is widely
used in municipal wastewater treatment, water supply and other fluid control systems.

Product features:
1. Simple valve structure Compared with other valves, the eccentric half-ball valve has a relatively simple structure,
requiring no complex transmission mechanisms. It is easy to operate and has low maintenance costs.
2. Flexible operation Influenced by mechanical principles, the design of the eccentric half-ball valve allows arbitrary
adjustment of the rotation angle, enabling highly flexible operation.
3. Excellent sealing performance The eccentric half-ball valve adopts a new-type sealing structure, featuring good sealing
and low leakage rate. The inner conical surface strengthens the fit between the valve body and cover, as well as between
the valve and seat, forming a sealed state.
4. Wide range of applications Due to its precise operation, the eccentric half-ball valve is widely used in various fields,
such as urban water supply and drainage, petrochemical, metallurgy, power, and other industrial sectors—with the
chemical industry being the most extensive application area.
