Water Treatment Valve Suppliers & Manufacturers in China

Water treatment plants rely on valves at almost every stage: intake and raw-water lines, coagulation and sedimentation, filtration, disinfection, sludge handling and treated-water distribution. The duty is not just on/off isolation — buyers also need throttling, backflow protection, isolation for maintenance and reliable shut-off against dirty or abrasive media.

When comparing water treatment valve suppliers, look at the valve type (gate, butterfly, ball, globe, check or control), the body and seat materials, the pressure class, the end connections and the actuator. Media matter: raw water, wastewater, sewage and sludge can carry solids and debris, so a resilient-seated butterfly or a non-clogging gate valve may suit better than a tight-clearance control valve.

The list below collects products whose names, descriptions or published parameters mention water, wastewater, sewage, water treatment or municipal water; use the filters to narrow the range, open a product for its parameters, and ask the exhibitor for drawings and service references. The 2027 Wenzhou valve exhibition brings these suppliers together; pre-register for a free visitor badge and bring your plant's flow and media data.
