A manufacturer and exporter of valves and fire-protection equipment, with our own production lines in the heart of China's plumbing and valve industry.
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. We manufacture and export valves, fire-fighting equipment, fluid-control equipment and integrated solutions for industrial, municipal, fire-protection, water supply and drainage sectors, and our engineers support product selection and customization on every order.
Our own production lines in Quanzhou, Fujian combine a senior engineering team with in-house CNC machining, assembly and pressure testing — supported by qualified manufacturing partners for selected items. Valve bodies are CNC-machined in-house, every unit is shell pressure-tested and air-leakage tested before shipment, and production runs under an ISO 9001 quality management system together with the relevant national industrial standards, ensuring the stability, reliability and durability of each product.
Our catalogue is built around the specifications design engineers actually work from — pressure class, connection standard, body and trim material, and application — with inquiry-based quotations and technical support for water supply, industrial fluid control, and firefighting projects.
Documents and footage for your due diligence — the same records our own buyers verify. Ask us for the full certificate and test-report package matched to your PO.
Twenty-five seconds of unedited footage from our own production lines — sheet-metal bending, welding, the powder-coating line and fire-hose jacket weaving. No stock video.
Verification is a normal part of doing business with a Chinese supplier. Here is what we will put in your hands before you commit — ask for all of it.
