ball check valve

    Spherical check valve is a special type of check valve, whose core component is a rubber wrapped ball that can roll up, down, left, and right on the slide inside the valve body to control the opening and closing of the valves. The main function of a spherical check valve is to prevent the backflow of the medium in the pipeline, avoid the occurrence of water hammer, and protect the pipeline system from damage. Due to its unique structural design, spherical check valves have many performance characteristics that are superior to traditional check valves. 

Characteristics of spherical check valves

• Efficient sealing performance: The sealing surface of the spherical check valve adopts a spherical design, which fits tightly with the valve seat, effectively reducing leakage and ensuring that the fluid will not flow back when the valve is closed.
• Low fluid resistance: The spherical design reduces the resistance experienced by the fluid when passing through the valve, which is beneficial for reducing system energy consumption and improving fluid transmission efficiency.
• Automatic control: The spherical check valves automatically opens and closes based on the flow pressure of the medium itself, without the need for an external power source, making it suitable for unmanned or remotely controlled systems.
• Wear resistant and long-lasting: The sealing surface and stainless steel structure seat of the spherical check valve are made of wear-resistant materials, which can withstand high-speed fluid impact and long-term operation, thus having a longer service life.
• Shock absorption and noise reduction: During the valve closing process, the spherical sealing surface can gradually contact and compress the valve seat, reducing the energy generated by fluid impact, lowering system noise, and protecting pipelines and equipment.
• Wide applicability: Spherical check valves are suitable for various fluid media and pipeline systems such as HDPE pipe and PVC pipe, including high temperature, high pressure, corrosive media, etc., and have high versatility.
• Easy to install and maintain: The structure of the spherical check valve is relatively simple, and installation and maintenance are relatively convenient, which helps to reduce the installation and maintenance costs of the entire system.
