CHINA JOEPAI manufacturer of 2-piece Korea type threaded ball valve. Available in SUS304(CF8), SUS316(CF8M) materials. Full port, anti-blowout stem, PTFE, RPTFE or PPL seat. Ideal for water, gas, oil, and chemical applications.
The 2-piece Korea type ball valve is a type of threaded (screw) end ball valve, widely used for on/off control of various media. As a compact and reliable solution, the threaded ball valve operates by rotating a ball with a cylindrical bore. The valve body connects to pipelines via internal threads (screw threads), ensuring easy installation and maintenance.
Compared with one-piece (monoblock) or three-piece designs, the two-piece structure offers a balanced combination of easy maintenance and leak-tight performance, making it the most popular choice for industrial applications.
The valve is operated manually (lever handle). Rotating the stem by 90° drives the ball to open or close:
Open position: ball bore aligned with pipe axis → media flows through.
Closed position: ball bore perpendicular to pipe axis → media is blocked.
Full port design – minimal pressure drop, easy pigging;
Two-piece body construction – easy to maintain, high reliability
Anti-blowout stem design – enhanced safety under pressure
Elastic ball sealing structure – reliable sealing even under temperature/pressure fluctuations
Investment casting – precise dimensions, smooth surface finish
Wide material selection – SS304, SS316, SS316L
Seat materials: PTFE, RPTFE (Reinforced PTFE), PPL – suitable for various media
Size range: DN6 – DN100 (1/4" – 4")
Pressure rating: JIS10K, JIS20K, 600WOG (PN40), 1000WOG (PN63)
