Is the sealing performance of brass ball valve easily affected by external factors?

In addition to temperature, pressure, fluid type and environmental factors, the sealing performance of brass ball valves may also be affected by other factors, such as operating frequency, improper installation, and wear after long-term use. Operating frequency has a certain impact on sealing performance. Frequent opening and closing actions may cause wear or fatigue of the sealing ring, especially without proper lubrication or maintenance, the sealing material will gradually lose elasticity, resulting in a decrease in the sealing performance of the valve. Therefore, regular inspection and maintenance are essential to maintain the sealing performance of the valve.
Improper installation is also an important factor affecting the sealing performance of brass ball valves. If the flatness of the connection between the valve body and the pipeline is not ensured during installation, or the sealing surface is squeezed by external force, the sealing effect will be greatly reduced. Installing non-compliant ball valves may cause asymmetric sealing surfaces and increase the risk of leakage. In addition, if the sealing surface is not properly aligned during installation, it will also cause poor contact, resulting in incomplete sealing.
In the long-term use of brass ball valves, due to the scouring of fluids and high-frequency opening and closing, the sealing material may gradually wear, especially under high flow rate and high pressure conditions. Over time, the sealing ring and seat surface in the ball valve may be damaged by friction, cracked or worn, resulting in reduced sealing performance. Although brass itself has good corrosion resistance, under some special working conditions, such as high-flow liquid or fluid containing particles, the surface of the brass ball valve may also suffer mechanical wear and corrosion, affecting the sealing effect.
The design and manufacturing quality of the brass ball valve also have a direct impact on the sealing performance. The contact surface between the ball and the valve seat of the ball valve must be precisely machined to ensure the fit and sealing effect between the two. If the manufacturing accuracy is not high, the contact surface may be uneven, resulting in incomplete sealing. Even small manufacturing defects may lead to reduced sealing performance and even leakage problems. Therefore, choosing a ball valve with good quality control and precision manufacturing process is the key to ensure sealing.
The sealing performance of the brass ball valve is also affected by maintenance. If it is not maintained or inspected for a long time, the sealing parts may be blocked by dirt, impurities or corrosive substances, resulting in poor sealing. Especially in some corrosive, scaling or solid particle-containing fluid applications, the sealing parts of brass ball valves are easily contaminated, which in turn affects their normal operation.
