Yihe steel balls play a crucial role in sealing applications by utilizing their precise spherical shape and high-strength materials to prevent leakage of liquids or gases. Based on customer use cases and online research, the following summarizes the sealing applications of steel balls:

Hydraulic Systems:

Micro steel balls are used in hydraulic systems, specifically in check valves or pressure control valves. They achieve sealing by precisely fitting into the valve seat, preventing hydraulic fluid from flowing backward or leaking.

Pneumatic Systems:

Steel balls are used as valve components in pneumatic devices. Their role is to control the airflow and pressure by effectively sealing off the flow when required.

Pump Equipment:

In various pumps, such as water pumps, oil pumps, and fuel pumps, steel balls are key components in check valves. They ensure unidirectional fluid flow and achieve efficient sealing.

Nozzles and Precision Instruments:

In applications requiring high-precision sealing, such as small nozzles and precision instruments, micro steel balls contribute to sealing and flow regulation through their tight fit with other components.

In these applications, it is essential to ensure that the steel balls' size and roundness precisely match the sealing components to achieve gap-free sealing. This prevents leakage of liquids or gases. Additionally, the steel ball material must resist corrosion from the fluid or gas, ensuring a long service life. The roughness of the ball should also be smooth, ensuring quiet operation. Since the balls are sometimes exposed to the external environment, their appearance must have a high gloss and excellent surface finish.

Case Examples:

Automotive Industry: In fuel injection systems, steel balls are used to control fuel injection, sealing and regulating fuel flow.

Medical Devices: In infusion pumps and injection devices, micro steel balls serve as sealing elements, ensuring the safe transport of medicinal fluids.

Aerospace: Steel balls are used in high-precision sealing valves, ensuring sealing performance in extreme conditions.
