Import Bronze Stop Valve — Buy in wholesale FOB from Supplier in China

The bronze stop valve from Taizhou Zhenggong Bronze Wares Co., Ltd. is a threaded-end globe-style valve cast from copper alloy bronze ASTM B62 C83600, a leaded tin bronze containing approximately 83-86% copper, 4-6% tin, 4-6% lead, and 4-6% zinc by weight. This composition delivers inherent resistance to dezincification and seawater corrosion, making it suitable for potable water, marine, and light hydrocarbon service. The valve carries a 200 WOG (water, oil, gas) pressure rating and utilises BSP or NPT threaded connections for direct integration into standard iron or copper pipe systems. Typical sizes range from 1/2 inch to 4 inches nominal bore, with larger diameters available on request.

ASTM B62 C83600, also known as 85-5-5-5 bronze or simply valve bronze, is the standard material for plumbing and low-pressure steam valves where ease of machining and pressure tightness matter more than high strength. The lead content improves machinability and wear resistance of the seating surfaces, while tin adds hardness and corrosion resistance. For drinking water applications, buyers should confirm compliance with NSF/ANSI 61 or the equivalent local potable water certification, as lead-content regulations vary by destination country. The valve body is typically sand-cast then machined to accept renewable or non-renewable disc and seat arrangements depending on the trim class ordered.

This valve type is purchased by plumbing wholesalers, HVAC contractors, ship chandlers, and municipal waterworks in the Middle East, Southeast Asia, and Africa. Common applications include isolation on hot and cold water distribution, fuel oil lines, compressed air systems, and low-pressure steam circuits up to 200 psi saturated. Before ordering, confirm the thread standard (BSP parallel or taper versus NPT), desired handle material (malleable iron, steel, or aluminium), and whether the disc is required to be non-rising or rising stem. The supplier lists the product under HS Code 8481.80; buyers should verify with the supplier whether mill test certificates or third-party inspection reports are available.

Taizhou Zhenggong Bronze Wares Co., Ltd. is located at No.5 Zone 3, Sanitary Industry, Luqiao, Taizhou, Zhejiang Province, 318054, China. The company holds an imported supplier tier and harbour trust tier on the platform. The response rate is recorded at 0.00% with zero average response hours, which indicates that direct communication has not yet been established through the platform messaging system. Buyers should plan to reach out proactively via alternative contact methods provided on their profile or during trade show meetings.

The supplier's address places them within Taizhou's concentrated plumbing and sanitary hardware manufacturing cluster in coastal Zhejiang, a region with deep supply chains in brass and bronze valve casting. The listing does not state years in operation, factory floor space, headcount, annual revenue, specific client references, or third-party certification holdings such as ISO 9001. Any claims about quality management systems, production capacity, or major export markets should be verified directly with the supplier and supported by copies of current certificates before order confirmation.
