JIS 20K Stainless Steel Ball Valve DN20, DN40, DN50 – High Pressure Ball Valve for Industrial Piping Systems

✅ JIS 20K Stainless Steel Ball Valves DN20, DN40, and DN50 are designed for high-pressure industrial applications requiring reliable shut-off performance and long service life. Manufactured in accordance with the JIS 20K flange standard, these valves are widely used in water treatment, steam systems, compressed air, oil & gas, chemical processing, food production, and industrial automation.

✅ The valve body is manufactured from SS304 or SS316 stainless steel, providing outstanding corrosion resistance, oxidation resistance, and mechanical strength. For highly corrosive media such as seawater and aggressive chemicals, the SS316 version offers superior durability and long-term reliability.

✅ Featuring a 90-degree quarter-turn ball mechanism, the valve provides fast opening and closing with low operating torque and excellent sealing performance. Its Full Port (Full Bore) design minimizes pressure loss while allowing maximum flow capacity through the pipeline.

✅ High-quality PTFE (Teflon) or RPTFE seats ensure excellent sealing performance, chemical resistance, and extended service life. The precision-machined and polished stainless steel ball reduces friction and delivers smooth, dependable operation throughout the valve's lifespan.

✅ Available in DN20 (3/4 inch), DN40 (1-1/2 inch), and DN50 (2 inch) sizes, the valve features JIS 20K flanged connections, ensuring compatibility with high-pressure piping systems widely used across Asia. In addition to manual lever operation, the valve can be equipped with electric actuators or pneumatic actuators for automated process control.

✅ Combining high-pressure capability, corrosion resistance, reliable sealing, and minimal maintenance requirements, the JIS 20K Stainless Steel Ball Valve DN20, DN40, and DN50 is an excellent solution for demanding industrial fluid control applications.
