Established in July 1984, we are a specialized solenoid valve manufacturer. Starting with the domestic production of solenoid valves for factory automation, pressure switches, and alarm switches for automatic fire extinguishing systems, we primarily develop and produce fluid control-related products. Through continuous research and development, we have registered numerous patents, utility models, and designs, and have obtained CE and explosion-proof certifications, demonstrating our technology and quality. We are also increasing our brand awareness in both domestic and international markets with our unique brand, "Autosigma." Leveraging our expertise in solenoid valves, we launched a product line for gas combustion equipment, including gas solenoid valves, in 2016. In 2020, we launched irrigation valves, essential equipment for building smart farms, a key component of the Fourth Industrial Revolution. We already dominate the domestic market, competing with leading international brands for irrigation and horticulture valves, and we are committed to supporting smart farm operations for domestic farmers with superior quality and price.
