Import Check Valve — Buy in wholesale FOB from Supplier in China

Suzhou Nova Valve Flow Control Co., Ltd. supplies check valves in nominal sizes from 1/2" to 48" (DN15 to DN1200) with pressure ratings spanning 150LB to 2500LB, designed to standards including BS1868, API602, and ASME B16.34. The range covers lift check, swing check, and dual-plate variants, each engineered for unidirectional flow control in industrial piping systems. Design features include bolted bonnet or optional pressure seal bonnet, hinge-mounted retaining rings to reduce leakage points, and optional cobalt-free hard facing for extended service life.

Materials are selected for durability in high-pressure applications, with body and bonnet connections designed to minimise maintenance downtime. The lift check valve offers vertical flow control, while the swing and dual-plate designs provide low-pressure drop solutions for horizontal pipelines. Typical industry use cases include oil and gas, petrochemical plants, and water treatment, where non-return functionality prevents backflow and protects downstream equipment. Standard industry tolerances for valve seat leakage are Class IV or better under API 598, though exact test results should be confirmed with the supplier.

These valves are sourced by EPC contractors, plant engineers, and distributors requiring reliable flow control in critical systems. Common trade terms include FOB Ningbo or Shanghai, with packaging typically as wooden crates for export. Buyers should verify compliance with project-specific standards, as Suzhou Nova’s offerings align with international norms but may require additional certification for regional codes. Lead times and MOQs are negotiable based on size and material specifications, with bulk orders often prioritised for faster delivery.

Suzhou Nova Valve Flow Control Co., Ltd. operates from an industrial facility in Taiping Street, Suzhou, Jiangsu Province, China. The company specialises in flow control solutions, with a product portfolio that includes check valves, gate valves, and globe valves for industrial applications. Its harbor-tier trust status reflects verified contact details and a physical address, though the current response rate and average response time are not publicly available.

The supplier’s focus is on engineering valves that meet international standards such as BS, API, and ASME, catering to industries like oil and gas, chemical processing, and water management. The listing explicitly highlights design features such as bolted bonnet connections and hinge-mounted retaining rings, which are critical for reducing maintenance and leakage risks. No additional history, client list, or headcount is provided in the available data, and buyers should confirm operational capabilities directly with the supplier.
