Import Ball Valve — Buy in Bulk from Supplier in China

Dawoo Valve Co., Ltd manufactures a brass ball valve intended for fluid control across residential, commercial, and light industrial applications. The valve body is cast from brass, an alloy primarily of copper and zinc, offering machinability and reasonable corrosion resistance in water and non-aggressive media. Its quarter-turn operation allows rapid opening and closing with minimal torque. The design targets minimal pressure drop, though the supplier does not publish exact Cv values or Kv coefficients. Size options and exact pressure ratings are not specified in the source data and must be requested directly from the Zhejiang-based manufacturer.

Brass ball valves in the general market typically utilise brass grades such as CW617N (CuZn40Pb2) or dezincification-resistant CW602N for potable water compliance. Seats are commonly PTFE or similar fluoropolymer, while seals may be EPDM, NBR, or PTFE depending on temperature and chemical exposure. Threaded ends usually conform to ISO 228 (BSP parallel) or ISO 7 (BSP taper), with American markets often requiring NPT. Dawoo Valve Co., Ltd states compliance with international standards but does not identify the specific norms, so buyers should request test reports and standard references. The valve's suitability for gas service depends on certification to regional standards such as EN 331 or ANSI Z21.15, which must be verified.

Applications span plumbing distribution, heating and HVAC circuits, irrigation systems, and general fluid isolation where bronze or stainless steel would be unnecessarily costly. Contractors, maintenance firms, and plumbing wholesalers represent the core buyer segments. The company, situated in Yuhuan, Zhejiang Province, a region with significant valve and fitting manufacturing concentration, offers flexible minimum order quantities and FOB or CIF shipping. No response data is available on the profile, making direct enquiry the only reliable channel for current pricing, stock levels, exact lead times, and certification validity.

Dawoo Valve Co., Ltd operates from Longxi Industry Zone in Yuhuan, Zhejiang Province, China. Yuhuan is recognised as a major cluster for valve, fitting, and plumbing product manufacturing, providing access to extensive supply chain infrastructure. The supplier holds an imported tier and harbor trust tier on its platform profile. Its response rate and average response hours are both recorded at zero, indicating no platform-mediated communication history. Prospective buyers should contact the company directly to evaluate responsiveness and technical support capability.

The profile does not disclose founding year, factory floor area, employee numbers, annual output, or named customers. No revenue or export volume data is presented. The listing asserts ISO certification and compliance with international standards for the brass ball valve, but does not specify which ISO standard (for example, ISO 9001 quality management) or the certifying body. Buyers should obtain valid certificate copies and verify scope. Dawoo Valve Co., Ltd offers flexible MOQ, competitive pricing, and FOB or CIF shipment terms, though exact quantities, price bands, and named ports require direct confirmation.
