API Fixed Ball Valve
The API Fixed Ball Valve is designed for high-pressure and high-temperature applications in oil, gas, and petrochemical industries. Its trunnion-mounted ball reduces seat wear, enables bubble-tight sealing, and lowers operating torque. Robust materials, fire-safe options, and customizable configurations provide dependable service in demanding pipelines and process systems.
API Fixed Ball Valve
API Fixed Ball Valves are engineered to provide reliable isolation, precise flow control, and long-term operational safety in high-pressure pipelines. The fixed/trunnion-mounted ball design minimizes seat wear, ensures low operating torque, and maintains tight shutoff under extreme conditions. Manufactured from high-quality carbon steel, stainless steel, alloy steel, and duplex materials, the valve is suitable for oil, gas, steam, and chemical media.
The valve integrates easily with gear operators or electric actuators, supporting automation in industrial pipelines. Fire-safe, anti-static, and DBB (Double Block & Bleed) configurations are available, meeting the stringent requirements of API 6D, API 608, and international standards.
