Import Bacv Series Brass Swing Check Valves — Buy in Bulk from Supplier in China

The BACV Series Brass Swing Check Valves from Zhejiang Banninger Fluild Control Co., Ltd. are non-return valves with a swing-type disc mechanism designed to prevent backflow in water, ethylene glycol, and non-corrosive medium systems. The nominal diameter spans DN15 to DN50 (equivalent to 1/2 inch to 2 inch), with a nominal pressure rating of PN 16. Thread connections conform to BS EN 10226 (ISO 7) or ISO 228 standards, ensuring compatibility with common European and international piping systems. Sealing test pressure is 1.1 times PN, while shell test pressure reaches 1.5 times PN, reflecting standard hydraulic valve testing protocols for pressure boundary integrity.

These valves are constructed from brass, an alloy primarily of copper and zinc that offers good machinability, corrosion resistance in water service, and reasonable cost for commercial and industrial applications. The temperature range of -5 degrees Celsius to +85 degrees Celsius suits typical building services, HVAC circulation, and process water systems where freeze protection or moderate heat is present. The swing disc design allows full flow when open and relies on gravity and reverse flow momentum to seal, making it simpler and more economical than spring-loaded or piston alternatives for horizontal installations. Standard material grades for brass valve bodies typically follow EN 12165 or ASTM B124 specifications, though buyers should confirm the exact alloy composition with the supplier for specific compatibility requirements.

Primary applications include hot and cold water distribution, heating systems with ethylene glycol mixtures, and general industrial non-corrosive fluid handling. Typical buyers are plumbing wholesalers, HVAC contractors, mechanical engineering firms, and water treatment system integrators sourcing for commercial building projects. The BS EN 10226 thread form provides a pressure-tight metal-to-metal seal on tapered threads, while ISO 228 parallel threads require additional sealing elements such as gaskets or thread sealant. Buyers should confirm minimum order quantities, available stock configurations, and whether Banninger offers custom end connections or valve modifications for OEM requirements.

Zhejiang Banninger Fluild Control Co., Ltd. is located at No. 555 Zonglv Road, Brige District, Haiyan County, Jiaxing, Zhejiang Province, China, postal code 314305. The company operates within the harbor trust tier on the platform, which reflects a baseline verification status rather than an advanced assurance level. The response rate is recorded at 0.00 percent with zero average response hours, indicating that communication signals from this supplier are currently absent or not tracked through the platform's messaging system. Buyers should initiate direct contact to assess responsiveness and clarify whether this reflects a data gap or actual communication practices.

The supplier's listing focuses specifically on the BACV Series Brass Swing Check Valves, suggesting a product-specific or catalogue-based offering rather than a broad valve manufacturing portfolio. No verified certifications, factory audit reports, or additional product lines are stated in the available profile data. The address places the company in Jiaxing, a region within Zhejiang Province known for metalworking and fluid control component manufacturing clusters. Buyers should request company registration documents, quality management system certificates such as ISO 9001, and product-specific test reports to validate manufacturing capability and quality control processes before committing to orders.
