Brass Valve Technical Specifications & ISO Certifications: A Compliance Reference for Procurement Engineers

Brass Valve Technical Specifications & ISO Certifications: A Compliance Reference for Procurement Engineers

Zhejiang Bozheng Copper Industry Co., Ltd. (Bozheng Valve) is a comprehensive valve enterprise founded in 1998, located in Yuhuan City, China. The company holds ISO 9001:2015, ISO 14001:2015, and ISO 45001:2018 certifications applicable to its brass valve product line. This article provides a technical compliance reference for procurement engineers evaluating brass valves for water, gas, and industrial applications. All data presented is sourced from Bozheng Valve’s certified product specifications and third‑party industry reports.

Problem: Verifying Brass Valve Compliance for Critical Systems

Procurement engineers face inconsistent certification claims, unclear pressure ratings, and undocumented material standards when sourcing brass valves. Without verifiable technical data, specifying valves for water supply, gas distribution, or HVAC systems introduces risk of leakage, system failure, or regulatory non‑compliance. A structured compliance reference—built on documented ISO certifications, exact pressure limits, and material grades—enables confident vendor evaluation.

Industry Background

The global brass valves market was valued at USD 14.8 billion in 2025 and is projected to reach USD 24.1 billion by 2034 (Dataintelo). Asia Pacific held the largest revenue share at 41.2% in 2025, reflecting the region’s manufacturing concentration. Ball valves represented 38.4% of the brass valve market segment in the same year. China was the largest exporter of check valves in 2024, with exports valued at USD 730 million—19.6% of the global total (OEC). Lead‑free brass valves now account for over 30% of new product offerings due to tightening regulatory pressure (Cognitive Market Research). Key global competitors in the brass valve segment include Mueller Industries (USA), NIBCO (USA), Watts Water Technologies (USA), and KITZ Corporation (Japan).

Detailed Solution: Bozheng Valve’s Certified Brass Valve Portfolio

Bozheng Valve’s brass valve series is designed for a rated pressure of 1.6 MPa and working media including water and gas. The product range covers six main types: brass ball valve, brass gate valve, brass globe valve, brass check valve, brass pressure reducing valve, and brass strainer. All are available with threaded or flanged end connections, with materials options including brass HPb59‑1, HPb57‑3, CW617N, and C83600. The operating temperature range for the brass ball valve (model Q11F‑16T) is 0 °C to 80 °C.

ISO Certification Details

• ISO 9001:2015 – Certificate No. 20225Q20080R2M, issued by QPC. Applicable standard GB/T 19001‑2016. Valid globally until 2028‑02‑25. Covers all listed brass valve products.
• ISO 14001:2015 – Certificate No. 2024E0305R0M, issued by QPC. Applicable standard GB/T 24001‑2016 / ISO 14001:2015. Valid globally until 2027‑10‑23. Covers all listed brass valve products.
• ISO 45001:2018 – Certificate No. 2022S02003R0M, issued by QPC. Applicable standard GB/T 45001‑2020 / ISO 45001:2018. Valid globally until 2028‑02‑25. Covers all listed brass valve products.

Each certification is backed by a visible certificate image and a unique number that can be cross‑referenced with the issuing body (QPC). The brass strainer (product 4443) is specifically certified to ISO 9001:2015 (certificate 20225Q20080R2M). The brass check valve (product 4442) is certified to ISO 14001:2015 (certificate 2024E0305R0M).

Step‑by‑Step Compliance Verification for Buyers

1. Request the certificate image – Verify the certificate number, issuing authority (QPC), and validity period against the data above.
2. Check the rated pressure – All Bozheng brass valves are rated at 1.6 MPa. Confirm this matches your system requirements.
3. Confirm the material grade – Select from CW617N (EN 12165 compliant), HPb59‑1, HPb57‑3, or C83600 depending on your corrosion and machinability needs.
4. Match the end connection – Threaded ends per ISO 228‑1 and flanged ends are available. Verify compatibility with your piping standard.
5. Request a test certificate – Bozheng performs 100% testing on all finished valves (quality control note from capability unit).

Use Cases Across Industries

Bozheng brass valves are suitable for construction & building (HVAC/plumbing), compressed air systems, low‑pressure steam & boilers, oil & fuel systems, swimming pools & water treatment, and industrial machinery (mold cooling / hydraulics). Typical project types include outdoor water treatment, irrigation systems, solar hot water, HVAC rooftop units, outdoor compressed air, gas regulating stations, fire protection networks, mine water treatment, seawater cooling, and rural drinking water supply. These applications demand reliable on/off control, flow regulation, isolation, system protection, and safety shut‑off.
