ANSI Lifting Plug Valve with Flanged Connection

Structure: Plug valve is a rotary valve with a closure or plunger shape. It is a type of valve that opens or closes by rotating 90 degrees to make the channel port on the valve plug the same or separate from the channel port on the valve body.

Material: The valve is constructed from high-quality stainless steel, providing excellent corrosion resistance and durability for use with a wide range of industrial fluids.

Operation: The Stainless Steel Threaded Ball Valve can be operated manually using a handle or lever for simple and reliable flow control.

Sealing Performance: The valve is equipped with reliable sealing components to ensure tight shut-off and prevent leakage, maintaining the integrity of the pipeline system.

Application Range: The Stainless Steel Threaded Ball Valve is suitable for controlling the flow of various fluids, including water, oil, gas, and other compatible mediums in industrial applications.

Operating Environment: The valve is designed to operate effectively in normal, medium, and high-temperature environments, meeting the fluid control requirements of different industrial processes.

Application Fields: The Stainless Steel Threaded Ball Valve is commonly used in industries such as chemical processing, oil and gas, water treatment, and HVAC systems for reliable fluid control and shut-off.

Frequently Asked Questions（FAQs）

Q:When should a plug valve be used?
The application scenarios of plug valves are well-defined, primarily occurring in situations where rapid on/off control of fluid pipelines is required or periodic flushing of pipeline impurities is necessary.

Q:What specific areas are involved?
For instance, pipelines in the petroleum and chemical industries that transport corrosive oils/gases or chemical slurries, as well as sewage conveyance lines handling wastewater containing sediment impurities, all require flushable plug valves with excellent sealing performance and erosion resistance for effective control.

Why Choose Us?

Our core advantage stems from our dual expertise in material selection and manufacturing processes: The entire valve body is cast as a single piece from food-grade or industrial-grade stainless steel, offering corrosion resistance far superior to that of conventional cast iron valves. It ensures long-term stable operation under complex conditions such as acidic/alkaline environments and high humidity without experiencing rusting or leakage issues. The plug sealing surface undergoes precision grinding and features a self-tightening seal structure, enabling effortless operation while maintaining zero-leakage sealing performance over extended periods—resulting in a service life exceeding that of standard plug valves by over 30%. Additionally, our products can be customized for specific application requirements regarding bore size, pressure rating, and connection type. Each batch undergoes rigorous pressure and seal integrity testing before shipment, making them suitable for various applications including chemical processing, food handling, and water supply/drainage systems. Our after-sales team provides on-site support within 72 hours to address all aspects of installation, commissioning, and maintenance.
