Our pneumatic flanged 3-way ball valve is a heavy-duty, automated flow control solution engineered for industrial processes requiring precise, remote media diversion, mixing, and splitting. Available in both L-port and T-port flow configurations, this valve is purpose-built for high-demand pipeline systems that require reliable, fast-acting automated control, with a flanged connection design that ensures rigid, leak-proof installation in high-pressure and large-diameter applications.
The working principle centers on a pneumatic actuator that drives the ball core through a 90-degree rotational stroke, adjusting the flow path within the valve body. L-port configurations are optimized for flow diversion, enabling seamless switching of media between two outlet pipelines, while T-port configurations support simultaneous flow mixing, splitting, or distribution across three pipeline lines. The valve’s full-bore design minimizes flow resistance, ensuring high flow efficiency and reduced pressure drop across the pipeline.
Equipped with high-performance double acting or spring return pneumatic actuators, this valve delivers fast, consistent response times for remote automated control, ideal for continuous industrial production lines and process automation systems. It supports seamless integration with DCS and PLC control systems, enabling fully unattended operation.
With both L-port and T-port flow path options, this flanged 3-way ball valve adapts to a wide range of process requirements, from simple flow diversion to complex media mixing and multi-line distribution, eliminating the need for multiple single-way valves and reducing system complexity and cost.
The valve features a standard flanged connection design, compliant with global industry standards, ensuring a rigid, vibration-resistant seal that maintains integrity even in high-pressure, high-temperature, and heavy-vibration industrial environments. This design eliminates the risk of connection loosening, making it ideal for long-term continuous operation.
This pneumatic 3-way ball valve is trusted by system integrators, industrial plant operators, EPC contractors, and process equipment manufacturers across sectors including: oil and gas gathering and transportation, chemical refining, power generation, municipal water and wastewater treatment, pulp and paper manufacturing, metallurgy, marine and offshore, large-scale HVAC systems, and bulk material processing.
