Founded by a professional pump and valve engineer, we integrate innovative R&D, manufacturing, sales and services, serving as a manufacturer of industrial high-performance ceramic valves. Our main product range covers wear-resistant and corrosion-resistant ceramic ball valves, ceramic double gate valves, ceramic discharge valves, ceramic dry ash feed valves, ceramic rotary disc valves, ceramic blowdown valves, pneumatic dome valves, ceramic metal-seated butterfly valves, inflatable expansion butterfly valves, three-way ball valves for powder conveying and other series. Adhering to the business philosophy of “Quality-oriented, Innovation-driven”, we have obtained multiple utility model patents, and many products have passed provincial new product appraisal. Major processing equipment is sourced from well-known domestic and international brands. High-quality structural ceramics are adopted for ceramic components, enabling steady growth amid fierce market competition. Our valves are widely applied in severely abrasive and corrosive working conditions such as desulfurization & denitrification, pneumatic ash conveying in dust removal systems, pulverized coal transport, alumina powder transport, magnetic powder transport, coal washing plants, chemical plants and paper mills. Our valves can be manufactured in accordance with GB, ASME, DIN, GOST and other standards. They are widely used as cost-effective alternatives to expensive imported valves and exported to Southeast Asia, the Middle East, Australia, Europe, Russia, the United States and other regions.
