Products Description
This pneumatic three-way flange ball valve is an automated multi-port fluid control unit built for flow diversion, medium mixing and pipeline switching. Unlike ordinary 2-way ball valves that only perform simple on/off isolation, its integrated 3-port structure can replace two separate valves and complicated tee piping, cutting installation footprint and lowering potential leakage points. Fitted with a high-speed pneumatic actuator and precision machined L-type or T-type ball core, it achieves rapid remote flow direction switching. Flanged ends ensure stable, rigid pipeline connection for liquid, gas and low-viscosity media across continuous industrial processes.
Key Features
|
L & T Bore Optional Design Choose L bore for simple flow diversion or T bore for mixing and three-way distribution, adapting to different process logic. The polished ball surface reduces friction and guarantees reliable sealing performance. 01 High Response Pneumatic Actuator Double-acting or spring-return actuator available. Spring return version provides fail-safe position upon air loss, protecting the pipeline in emergency shutdown scenarios. ISO 5211 mounting pad supports simple actuator replacement. 02 Flexible Material Matching Body materials include WCB carbon steel, CF8 / CF8M stainless steel. PTFE, RPTFE or PEEK seat options support different temperatures and corrosive media. 03 Auxiliary Signal Accessories Available Limit switch, solenoid valve and air filter regulator can be pre-installed, enabling feedback of valve position and seamless integration with automated industrial control systems. 04

FAQ
Q: What media is this valve suitable for?
A: This valve is primarily engineered for handling high-viscosity, crystallizing and readily solidifying media such as asphalt, heavy fuel oil, paraffin wax, resin, chemical slurry and crude oil, alongside various other industrial process fluids. It enjoys extensive deployment within pipeline systems serving petrochemical, mining, thermal power, pharmaceutical industries and international infrastructure projects.
Q: How does the jacket insulation system work?
A: A full-enclosed outer jacket creates an independent thermal circulation chamber. By introducing continuous heating media such as steam or thermal oil, the assembly maintains a steady operating temperature for both the valve body and internal process medium. This prevents temperature reduction and subsequent solidification of the medium during pipeline operation, sustaining smooth, uninterrupted fluid transportation.
Q: What material options are available?
A: We provide customized material solutions tailored to diverse working conditions. Our standard material portfolio includes stainless steel grades 304 and 316L for anti-corrosion service environments, as well as WCB cast steel suited for high-pressure and high-temperature industrial applications. All incoming raw materials comply with relevant international industrial standards and deliver consistent, reliable performance.
Q: What connection and driving modes are supported?
A: We supply two mainstream connection configurations: flange and threaded ends, to satisfy diverse pipeline installation demands. As for actuation schemes, manual, pneumatic and electric actuators are all selectable, accommodating both on-site manual operation and automated intelligent control system integration.
Q: Is the valve leak-proof and durable?
A: Featuring a high-precision matched ball and seat assembly, this valve delivers reliable bidirectional tight sealing with extremely low leakage levels. Upgraded sealing components with superior wear and heat resistance effectively prolong overall service life. Every unit undergoes rigorous factory inspection and complies with ISO quality management standards, ensuring consistent stable performance during prolonged continuous operation.
Q: What is your product quality guarantee?
A: All our split-body jacketed ball valves are manufactured in stringent compliance with international industrial specifications. We offer long-term warranty and after-sales technical support. Equipped with full production qualifications and official ISO system certification, we are fully capable of delivering dependable valve products and consistent, reliable after-sales service to customers worldwide.
