The stainless steel ball valve is a universally applicable valve that plays a significant role in the valve industry. Given its widespread use, it represents a substantial portion of the market and requires considerable investment. Therefore, proper maintenance and protection of these valves can enhance operational efficiency while reducing repair times and saving costs.
To ensure the long-term stability and functionality of ball valves, it’s essential to pay attention to several key factors:
1. Before initial use, it’s advisable to rinse the pipeline and the valve body overflow with water. This helps remove any residual debris like iron filings that could potentially damage the valve's internal cavity.
2. When performing maintenance on a stainless steel ball valve in a closed state, remember that the medium inside the valve may still exert pressure. Always shut off the upstream valve before servicing. Open the ball valve to release all internal pressure. For electric or pneumatic ball valves, ensure the power supply and air supply are disconnected prior to servicing.
3. Ball valves with soft seals typically use PTFE as their sealing material, whereas hard-sealed ball valves feature metallic sealing surfaces. When cleaning a pipe ball valve, extra care should be taken to avoid damaging the seal rings and causing leaks during disassembly.
4. During the disassembly process, start by tightening the bolts and nuts on the flanges slightly before fully securing them. Forcing one nut into place before the other can damage the flange surface, leading to leaks when connecting the valve to the medium.
5. If the valve requires cleaning, use solvents that do not interact negatively with the parts being cleaned and won’t cause corrosion. Gas-only ball valves can be cleaned using gasoline, while other components can be cleaned with water. Ensure thorough cleaning to eliminate dust, oil, and other residues. If water isn’t sufficient, alcohol-based cleaning agents can be used without harming the valve body or parts. After cleaning, allow the cleaning agent to evaporate entirely before reassembling.
6. If minor leakage occurs around the stem packing during operation, gently tightening the stem nut can often stop the leak. Continue tightening until the leakage ceases.
7. Long-term exposure to environmental factors can lead to rusting of the valve body and components, rendering them unusable. Protect ball valves from rain, moisture, and humidity. Any valves stored for more than 12 months should undergo testing upon retrieval to ensure they remain functional.
This article draws insights from various sources in the valve industry. While the principles outlined here are widely accepted, specific practices may vary depending on the valve type and application.

While the above guidelines provide a comprehensive approach to maintaining stainless steel ball valves, it’s always recommended to consult the manufacturer's instructions for specific maintenance protocols tailored to your equipment. Proper upkeep not only extends the life of the valve but also ensures compliance with safety standards and operational efficiency.
