Our company primarily designs and manufactures a variety of flow control products, including butterfly valves, ball valves, check valves, globe valves, and gate valves, catering to multiple industries. Over more than a decade of continuous and stable development, we have cultivated a production team with professional technical skills and management experience. With rational design, scientific management, and rigorous testing, product quality has steadily improved.

Our company has successively obtained ISO9001 and ISO14001 quality system certification, TS special equipment production license, European PED-CE certification, French ACS certification for drinking water products, and more.

Since its establishment, our brand has been committed to producing high-quality and reliable products for customers, providing corresponding technical support, and offering standardized products as well as custom-made orders. Reliable quality and timely after-sales service are our guiding principles in serving customers.

We can produce valves according to various standards such as GB, BS, EN, ANSI, DIN, JIS, and others, based on actual needs. Quality control is strictly enforced throughout the design, manufacturing, and testing phases. Our products are widely used in industries such as HVAC, water treatment, chemical, power plants, and water supply systems.

From design to mold opening, casting, machining, production, and assembly, we follow our own drawings for acceptance. Stringent testing is conducted according to the national standard GB/T13927 before shipment. Since our establishment, we have obtained multiple patents and independently developed products, with no imitation or copying. With over a decade of manufacturing experience, the entire production process and quality control have matured, forming a complete inspection standard and quality control process from procurement to shipment. Currently, the annual production capacity of butterfly valves is approximately 100,000 units (including some supporting products).
