Five Chinese brass valve makers to watch in 2026

China remains the largest valve exporter as global brass valve demand grows, making supplier selection more important for international buyers. This guide profiles five established Chinese manufacturers and highlights the compliance, testing and certification checks buyers should verify before placing orders.

Why it matters: - Brass valve sourcing is expanding as the global market grows from USD 14.8 billion in 2025 to a projected USD 24.1 billion by 2034. - China is the largest valve-exporting country and accounts for an estimated 41% of global brass ball valve export shipments. - Buyers need suppliers that can prove scale, material compliance, certification coverage and export experience. - Lead-free requirements are tightening for potable water products in the U.S. and for gas and drinking-water valves in the EU.

What happened: - The report profiles five Chinese brass valve manufacturers: Zhejiang Longda Technology Co., Ltd., Ningbo Amico Group Co., Ltd., Zhejiang Dunyun Industrial Co., Ltd., Zhejiang Ruige Valve Group Co., Ltd. and Wandekai Fluid Technology Co., Ltd. - The companies were selected on manufacturing history, production capacity, product range, certification coverage and export orientation. - Zhejiang Longda Technology was established in 1993 and operates from YuHuan County, Zhejiang Province. - Longda reports a 30,000-square-meter factory, about 200 employees and annual production capacity of 7,500 tons. - Longda says roughly 95% of output is exported to the EU, U.S., Canada and South America.

The details: - Longda operates more than 360 sets of processing and testing equipment, including CNC machines, spectral analysis instruments, high-pressure testing sets and salt-spray test boxes. - Longda has more than 30 technical personnel, including six engineers in its R&D team. - Longda offers OEM/ODM service from tooling and design through production and testing. - Longda’s product range includes ball valves, gate valves, stop valves, check valves, heating valves, angle valves, Y-type strainers, bibcocks, faucets and brass fittings. - Longda uses brass alloys including Eco-Brass C69300, CW724R, lead-free C4650, CW511L, CW509L, CW510L and DZR CW602N. - Longda’s products are IAPMO and ALS certified, and key potable-water products carry cUPC and NSF/ANSI 61 and 372 certification. - The Model 8081 brass ball valve is a 2-piece full-port valve rated for 600 WOG and available from 1/2 inch to 4 inches with multiple connection options, including NPT, BSP, Press, PEX, Compression, SWT, ProPEX and Push-fit. - The T-22017A brass gate valve is a rising-stem, full-bore valve rated for 200 WOG and available from 1/2 inch to 4 inches. - The LD 30303 brass check valve uses lead-free DZR brass and is available with NPT, BSP, Press, PEX, MPT, SWT and Cold Expansion connections. - The LD.73154 brass Y-type strainer includes a blow-down drain plug and a replaceable SS304 screen in 20, 40, 60 or 80 mesh. - The 15111 brass pipe fittings series covers adapters, couplings, nipples, elbows, tees, unions, caps and plugs. - The 98023-LF brass supply stop valve is available in angle and straight versions with multiple connection types for faucet, toilet, washing machine and water-heater terminal applications. - Ningbo Amico Group is based in Ningbo, a major port city in Zhejiang and one of China’s largest foreign-trade hubs. - Zhejiang Dunyun Industrial is based in Zhejiang, within one of China’s primary brass valve production clusters. - Zhejiang Ruige Valve Group is a group-structured valve enterprise based in Zhejiang. - Wandekai Fluid Technology is positioned as a fluid-control technology supplier with a system-oriented approach.

Between the lines: - China’s brass valve base is concentrated in Zhejiang and Guangdong, which gives manufacturers access to forging, machining, surface-treatment and testing suppliers. - Compliance has become a competitive filter, not just a paperwork exercise, because buyers increasingly need product-specific certification and material traceability. - North American buyers often need NPT threads and certifications such as NSF/ANSI 61 and NSF/ANSI 372, while European buyers often require BSP threads and standards such as EN 331:2015 and EN 13828:2003. - The report’s emphasis on Longda’s testing equipment and export mix signals what many international buyers now prioritize: verifiable quality control, not just low-cost supply. - Technology-oriented suppliers such as Wandekai may appeal to buyers that need application support, custom configurations or system-level integration.

What's next: - Buyers are likely to keep narrowing supplier lists toward manufacturers that can document certification, alloy composition, testing and export readiness. - Demand for brass valves should continue rising with growth in potable water systems, HVAC retrofits and industrial fluid-control applications. - Chinese manufacturers that combine scale with compliance documentation are likely to remain key sourcing options for distributors, wholesalers and OEM buyers. - The market is projected to grow at a 5.6% compound annual growth rate through 2034, according to Dataintelo.

The bottom line: - Chinese brass valve manufacturers remain central to global sourcing, but buyers need to verify the product, not just the brand.
