What is a Manual Ball Valve?

A Manual Ball Valve is a quarter-turn valve operated by a lever or gear handle. Turning the handle rotates a ball with a central bore inside the valve body to either allow or block flow. With just a 90° turn, the valve switches between open and closed positions—ensuring fast, secure isolation of media in a wide range of pipelines.

Installation & Maintenance Tips

  • Always mount the valve with handle accessible
  • Operate periodically to avoid seat deformation
  • Apply anti-seize on threaded joints if reinstallation is expected
  • Check for leakage around stem seal; replace packing if needed
  • Flush valve after use in sticky or corrosive media

FAQs

Not recommended. Ball valves are designed for on/off control. For throttling, use V-port valves.

Yes—with the right seat (Graphite or TFM), they’re suitable up to 220°C.

Yes. We offer replacement handles, gear operators, and LOTO kits.

 

With proper use, our valves last 10–15+ years, even in harsh industrial environments.
