Yuhuan, Zhejiang, China – August 1, 2026 – Taizhou Dinglun Copper Industry Co., Ltd., a professional manufacturer and exporter of heating and plumbing hardware located in Chumen Town, Yuhuan City, known as China’s Valve Capital, has officially released its new Premium Brass Valve made of high-grade HPb57-3 brass, delivering long-lasting and reliable fluid control solutions for residential, commercial and industrial pipeline projects worldwide.
Established in June 2021 with registered capital of 3.68 million RMB, the company takes advantage of Yuhuan’s complete valve industrial cluster and convenient logistics access to Ningbo and Wenzhou ports. Equipped with CNC precision machining centers, automatic welding equipment and full-process pressure and leakage testing machines, Dinglun Copper Industry has built a strict ISO-standard quality management system covering raw material inspection, semi-finished processing and finished product multi-index testing.
The newly launched HPb57-3 brass valve serves as a core control component of Plumbing and Sanitary Ware. Adopting premium HPb57-3 brass raw material, it boasts outstanding corrosion resistance, anti-scaling and wear-resistant performance. Supporting nominal pressure up to 10 bar and maximum working temperature of 100°C, the valve is perfectly suitable for hydronic heating systems, domestic potable water pipelines and solar thermal circulation equipment. It realizes smooth and stable cold & hot water regulation, effectively eliminating pipeline leakage, balancing fluid flow and extending the whole service life of plumbing systems to cut frequent maintenance costs.
Featuring ultra-wide cross-series compatibility, this brass valve can be perfectly matched with Stainless Steel Manifolds to build multi-zone heating distribution circuits, seamlessly connected with pipeline frameworks assembled by Stainless Steel Pipe Fittings, and stably matched with Copper Valve Fittings and Copper Pipe Fittings for traditional copper pipe renovation works. When combined with Brass Angle Valves, it forms an integrated full-house water supply and heating control assembly. The compact body design allows easy installation in narrow and concealed spaces, while precision-machined thread connections create tight leak-free joints to avoid energy loss and expensive post-installation repairs. Every finished valve undergoes rigorous multi-round testing to meet international plumbing standards, bringing reliable usage guarantee to global installers and engineering purchasers.
