Adopts a high-strength forged body, a brass ball valve that can handle high-temperature steam up to 200°C. Ideal for steam piping in equipment and factories. <Made in Japan>

The gland section is equipped with double packing that has a high sealing effect. The conical spring prevents thermal deformation and a decrease in sealing surface pressure, allowing for long-term use. It features a long neck that makes it easy to wrap insulation material. Thanks to Hamai's latest valve technology, it is produced in our domestic factory. ■【Features】 - High temperature resistance up to 200℃ - Long neck for easy wrapping of insulation material - Conical spring prevents thermal deformation and decrease in sealing surface pressure - Safe structure that allows tightening of the gland nut by loosening the set screw in case of emergency - Made with PTFE, which has excellent corrosion resistance and durability ■【Product Quality Recognized by Professionals】 Hamai's ball valves are high-performance ball valves that boast a track record of mass supply (OEM) to various industrial equipment and machine tools, primarily for major manufacturers. They are adopted as genuine parts by various companies, meeting all the needs for ball valves with the highest product quality. ★【Custom Orders / Customization Available】 For more details, please contact [Tokyo Headquarters] TEL 03-3492-6655 <Receptionist / Second Sales>.
