Prevent accidents caused by unintended contact or vibrations that lead to handle opening and closing! The valve can be completely secured with a push-and-rotate mechanism, allowing for reliable switching between open and closed positions with just one touch.

Equipped with a unique locking mechanism that can securely fix the valve in fully open or fully closed positions with a single touch. This prevents accidents such as the handle unintentionally opening or closing due to contact with people or objects, or vibrations. The knob handle design is ideal for narrow piping. Thanks to Hamai's latest valve technology, these products are manufactured in our domestic factory and comply with RoHS standards. ■【Features】 - Equipped with a handle locking function. Ensures secure locking in fully open/fully closed positions. - Knob handle ideal for narrow piping. - High-strength integrated body made through hot forging. - Made with PTFE for excellent corrosion resistance and durability. - Anti-protrusion structure with the stem assembled from the inside of the body. ■【Product Quality Recognized by Professionals】 Hamai's ball valves have a proven track record of mass supply (OEM) to various industrial equipment and machine tool manufacturers, primarily among major companies, making them top-class high-performance ball valves in the industry.
