Yuhuan, Zhejiang, China – July 11, 2026 – Taizhou Dinglun Copper Industry Co., Ltd., a certified professional manufacturer and exporter of high-performance Plumbing and Sanitary Ware headquartered in Yuhuan, China’s renowned Valve Capital, has officially released its brand-new Versatile Brass and Plastic Pressure Regulation Kit, filling the gap of multi-specification adjustable pressure protection components in its full product lineup.
Founded in June 2021 with a registered capital of 3.68 million RMB, the enterprise boasts complete CNC machining production lines and strict full-cycle quality inspection standards. The newly launched pressure regulation kit adopts a hybrid composite structure, combining corrosion-resistant HPb57-3 brass main body and lightweight high-strength plastic internal parts, striking a perfect balance between structural robustness and cost efficiency. Developed by the company’s dedicated R&D team, the kit supports eight standard preset pressure levels covering 1.5bar to 10bar, which can effectively buffer pipeline pressure surges and safeguard the whole heating and water supply system.
In terms of stable operating performance, the product features a pressure tolerance of +10% for maximum opening pressure and -10% for minimum closing pressure, realizing long-term consistent pressure control. It adapts to cold and hot water dual-purpose environments and withstands continuous working temperatures up to 100°C, fully matching the operating parameters of the firm’s mainstream heating hardware including Stainless Steel Manifolds. The kit delivers seamless docking with pipeline frameworks built with Stainless Steel Pipe Fittings, and achieves reliable matching with Copper Valve Fittings and Copper Pipe Fittings for traditional copper piping renovation projects. When assembled with Brass Angle Valves, it forms a complete pressure protection assembly for floor heating, domestic hot water and commercial HVAC systems.
Mr. Ying, owner of Taizhou Dinglun Copper Industry Co., Ltd., shared insights on the new product rollout: “Global installers and end users are increasingly demanding cost-effective, multi-scenario pressure control accessories. Drawing on our mature supply chain cluster advantage in Yuhuan and strict incoming inspection of HPb57-3 brass and 304 stainless steel raw materials, we independently developed this hybrid brass-plastic pressure regulation kit. It integrates flexible pressure adjustment, wide material compatibility and easy installation, catering to residential DIY assembly, commercial pipeline maintenance and industrial fluid control demands.”
