    We specialize in two core industrial valve categories: gate valves (grooved/flanged, resilient & copper hard-seat) and butterfly valves (flanged/grooved/wafer, worm-gear driven, incl. fire supervisory switch models)- all in ductile iron.

    Seven key strengths: all ductile iron QT450-10, 2x gray iron strength; full connection coverage flanged/grooved/wafer/threaded; size range DN50-DN1200; five application scenarios (water treatment/fire/municipal/industrial wastewater/steam); differentiated supervisory switch butterfly valves; direct Nan'an, Fujian supply chain; low MOQ from 1 piece.

    Always a pre-production sample before mass production; Always final Inspection before shipment

    We are deeply tied to partner factories in the Nan'an valve cluster, Fujian. Casting, machining and assembly are fully traceable - we operate as a factory-direct style exporter with controlled quality and reliable delivery, not a simple middleman.
