Quanzhou Wanlian Fluid Equipment Co., Ltd. is located in Quanzhou, Fujian — the starting point of the Maritime Silk Road and the core cluster of China's plumbing and valve industry. As a professional fluid-equipment enterprise integrating R&D, sales and service, we focus on providing high-quality valves, supporting fire-fighting equipment, fluid-control equipment and integrated solutions for industrial, municipal, fire-protection, water supply and drainage sectors.
Based in Quanzhou, Fujian — the core cluster of China's plumbing and valve industry — Quanzhou Wanlian Fluid Equipment Co., Ltd. manufactures and exports industrial valves, hydraulic control products, hydrant components, and fire protection equipment for international B2B projects. Manufacturing runs on our own production lines in Quanzhou, with selected items produced by qualified manufacturing partners; valve bodies are CNC-machined and every unit is shell pressure and air-leakage tested before shipment, under an ISO 9001 quality management system.
We build every product page around the specifications buyers actually specify from — pressure class, connection standard, body and trim material, and application — with inquiry-based quotations and engineering support for water supply, industrial fluid control, and firefighting systems.
