Spherical check valve

Spherical check valve is a type of check valve that uses spherical valve discs as opening and closing components, and belongs to a novel automatic valve structure. Its core working principle relies on the flow and pressure changes of the medium itself to achieve opening and closing. The valve disc is a rubber coated sphere. When the medium flows forward, the fluid pushes the sphere to detach from the sealing surface of the valve seat, roll to the upper cavity of the valve body, and the valve opens; When the medium stops flowing or undergoes reverse flow, the sphere quickly rolls back to the valve seat under the action of gravity, reverse pressure of the medium, or backflow, achieving a tight seal. Kaiweixi Valve mainly produces vertical ball check valves, horizontal ball check valves, micro resistance ball check valves, ball check valves, etc. Ball check valves have extremely simple and compact structures, low flow resistance, and good sealing performance, especially suitable for media with high viscosity. Due to its unique spherical valve disc design, the requirements for installation position are relatively relaxed. It can not only be installed horizontally, but also reliably work in pipelines that flow vertically from bottom to top. Spherical check valves are widely used in pipeline systems in industries such as petroleum, chemical, pharmaceutical, and food, demonstrating good applicability.
