Pneumatic O-Type Shut-Off Ball Valves (On/Off Ball Valves) are commonly used in applications requiring rapid closure of pipeline media flow. Primarily composed of a single-acting pneumatic actuator and an O-type ball valve, they feature an emergency reset function. In the event of sudden failure or loss of air supply, the valve closes quickly to prevent media leakage. Powered by compressed air, the pneumatic O-type shut-off ball valve operates at high speed with precise opening/closing capabilities, ensuring complete fluid isolation within pipelines. It supports both local control and remote centralized operation, significantly enhancing operational safety.
