Products Description
Three-Piece Internal Thread Ball Valve belongs to the internal thread ball valve category, featuring a three-piece structure design (two end caps combined with a center body) connected by long bolts for easy disassembly and maintenance. The valve body is cast using technology introduced from Taiwan, ensuring a rational structure and aesthetically pleasing appearance. The valve seat employs an elastic sealing structure to ensure sealing performance, while the stem incorporates a bottom-mounted inverted seal design to prevent ejection in case of abnormal pressure buildup. Connection types include internal thread, butt weld (BW), and socket weld (SW), with driving options supporting manual, electric, and pneumatic operation.
The product has a nominal pressure range of PN1.0–4.0 MPa and is suitable for temperatures ranging from -29°C to 180°C (with reinforced PTFE seals) or -29°C to 300°C (with PPL seals), depending on the sealing material. The nominal diameter ranges from DN10 to DN100 (3/8" to 4"), and the main body materials include stainless steel (304/316) and carbon steel (WCB). It can handle media such as water, steam, oil, and nitric acid. The valve complies with manufacturing standards such as ANSI/ASME B16.34 and BS5351 and is widely used in pipeline systems across industries including chemical, petroleum, power, and food pharmaceuticals.

Performance Features
The three-piece thread ball valve offers the following performance characteristics:
Low Fluid Resistance: When fully open, the ball's flow channel aligns completely with the pipeline, resulting in minimal fluid resistance, a high flow coefficient, and a low flow resistance coefficient.
Excellent Sealing Performance: The valve seat employs an elastic sealing structure, ensuring tight contact between the ball and seat for reliable sealing and preventing medium leakage.
Simple Structure: The three-piece design makes the valve compact, lightweight, and easy to install and disassemble.
Easy Maintenance: Components such as the ball and seat are easily removable and replaceable, reducing maintenance costs.
Wide Range of Applications: Suitable for blocking or connecting media in pipelines. When made from different materials, it can handle various media, including water, steam, oil, nitric acid, acetic acid, and more.
