Pneumatic Actuated Flanged Ball Valve

Pneumatic Actuated Flanged Ball Valves are engineered for robust industrial piping systems, featuring a sturdy cast body, precision-machined ball and reliable seat sealing for long-term tight shut-off. The matched pneumatic actuator enables quick 90-degree quarter-turn operation, supporting fail-safe modes to meet process safety demands, and allows seamless integration with automated control systems for remote adjustment and emergency isolation. Flanged end connections simplify installation and maintenance, while optional soft and hard seal variants adapt to different temperatures, pressures and media conditions. These valves deliver low flow resistance and consistent performance, widely used across oil & gas, power, chemical and general industrial piping for daily automated flow control and pipeline safety management.

Application Scenarios

●  Petrochemical industry: Oil pipelines, refineries, chemical process lines, for flow control and emergency shut-off

●  Power & thermal systems: Steam, hot water and fuel pipelines, boiler and heating system control

●  Municipal gas pipelines: Natural gas transmission networks, pressure regulation and safety cut-off

●  Water treatment & environmental projects: Water supply, wastewater treatment and flue gas treatment lines

●  HVAC & district heating: Central air conditioning, circulating water and heating pipe networks

●  Metallurgy, paper, food & pharmaceutical industries: Production process pipeline control

●  Tank farms & terminals: Oil/chemical storage and loading pipelines, remote safety isolation

These valves suit automated pipelines requiring remote control, fast switching and emergency shut-off.
