The ball check valve offers several advantages, making it a preferred choice in various applications. Here are the key advantages:
High Flow and Low Resistance: The ball check valve is characterized by a large flow capacity and low resistance, contributing to efficient fluid transport.
Even Rolling Motion: The ball valve rolls evenly during fluid flow, making it particularly suitable for sewage discharge pipes containing suspended solids in both industrial and domestic applications.
Effective Cleaning Mechanism: The rolling action of the ball valve effectively cleans the channel and sealing surface, functioning as a self-cleaning mechanism for maintaining optimal performance.
Silent Closing: The check valve ensures silent closing during the closing process, preventing water hammer effects. This not only protects the sealing surface but also extends the valve's service life.
No Transmission Parts: The ball check valve features a free-opening and closing structure with no transmission parts. The absence of a drive shaft minimizes wear, as the ball automatically rotates and rolls in the spherical pipe, continuously updating the sealing surface.
Uniform Wear: In the presence of debris in sewage, any wear on the spherical surface occurs uniformly. This maintains high shape accuracy over time without compromising the sealing effect.
Elasticity and Vibration Absorption: The core of the ball check valve, often a hollow iron ball covered with rubber, provides elasticity during use. This feature allows the valve to absorb and reduce vibrations, enhancing its performance.
Narrow Sealing Surface: The spherical structure of the sealing surface is relatively narrow, resulting in higher sealing pressure and a more effective sealing effect.
Considering these characteristics, the ball check valve, especially those made of cast iron, proves to be an excellent choice for sewage pumping applications. It is often the standard configuration in high-end sewage lifters, ensuring optimal results and a prolonged service life during the sewage pumping process.
