Zhejiang Yonggao Valve Co., Ltd. (浙江永高阀门 / Yonggao Brass Valves)
Company Overview
Zhejiang Yonggao Valve is a brass valve and fitting manufacturer in the Yuhuan-Wenzhou area of Zhejiang, the cluster that supplies a large share of China's brass valves, brass fittings and low-pressure plumbing hardware. The region has an unusually complete local chain: brass ingot and bar suppliers, hot forging and die casting shops, machining, assembly and pressure testing, plus the plating and passivation workshops that serve them.
Yuhuan is worth understanding if you buy valves in volume. Because the forging, machining and testing steps are all local and often separate businesses, a factory here can scale quickly and can also quietly change a sub-supplier. That is the double-edged part of sourcing from a cluster: the capability is excellent, and the traceability requires your own discipline.
Main Products
Brass ball valves, gate valves, check valves and angle valves, along with brass fittings and manifolds for plumbing and HVAC distribution. Bodies are produced by hot forging or casting depending on size and pressure class; larger and higher-pressure bodies tend to be forged, smaller general-purpose items cast. Threading is offered in BSP (G) parallel or NPT taper to order.
The specification questions that matter most with a supplier in this category are the ones buyers most often skip: the alloy designation (free-cutting HPb59-1 is the cluster default and is not dezincification resistant), the pressure class and whether shell and seat tests are run on 100 percent of units, the ball and stem materials, the O-ring elastomer, and thread gauging. A factory that can answer all six in writing, with test data, is a different supplier from one that answers with a catalogue page.
Certification
Certification in this category is market- and alloy-specific. For European potable water applications, the relevant material and product approvals depend on the member state scheme; for North America, the applicable listing and low-lead compliance documentation apply. Ask for the certificate numbers with the product model list and verify them against the issuing body and the manufacturer's own documentation.
