Import Cvbp Series Backflow Preventers — Buy in Bulk from Supplier in China

The CVBP Series Backflow Preventers are axial-flow devices designed to prevent reverse flow in water and non-corrosive fluid systems. They are manufactured to AWWA C510 standards with a nominal diameter range of DN50 to DN300 (2" to 12") and rated for PN16 pressure. The design minimizes hydraulic loss and reduces overall system bulk, making them suitable for installations with space constraints. The operating temperature range extends from -5°C to 85°C, supporting use in both cold and warm water environments.

These devices use seals compliant with BS EN 12266-1 and API 598, ensuring leak-tight performance under pressure. The body and internal components are engineered for compatibility with water, ethylene glycol, and other non-corrosive media. Typical industry materials include ductile iron for the housing and EPDM for the sealing elements, which are standard for this class of backflow prevention. The loss-less flow path and compact footprint distinguish them from traditional double check valve assemblies.

They are commonly purchased by municipal water utilities, commercial building contractors, and industrial plant operators managing non-potable fluid systems. Buyers typically require certification to AWWA C510 and proof of shell and sealing tests conducted at 1.5PN and 1.1PN respectively. Packaging is standard in wooden crates with foam padding, and minimum order quantities are negotiable based on volume and delivery schedule. Lead times vary with production load and are confirmed at order placement.

Zhejiang Banninger Fluid Control Co., Ltd. is a manufacturer based in Haiyan County, Jiaxing, Zhejiang Province, China. The company specializes in fluid control valves and backflow prevention devices, with production facilities focused on industrial-grade valve assemblies. The listing shows a harbor-tier trust rating, indicating verified business registration and physical address, but no public data confirms production volume, employee count, or export history.

The supplier has not provided certifications such as ISO 9001, CE, or third-party audit reports. Response rate and average response time are not available on the platform, suggesting limited buyer engagement or internal capacity constraints. Buyers should treat this supplier as a direct manufacturer without verified quality management system documentation unless independently confirmed.
