Step-by-Step Production of Lead-Free Brass Valves
The production and assembly of lead-free brass valves involve precise engineering and careful material handling to ensure durability, safety, and compliance with health standards. Lead-free brass, primarily composed of copper, zinc, and other trace elements, is widely used to reduce health risks in plumbing systems, making these valves suitable for potable water applications.
The production process begins with the selection and preparation of high-quality lead-free brass. The raw material is melted in furnaces and cast into valve blanks using molds designed for specific valve types, such as ball valves, gate valves, or check valves. This casting step ensures the basic shape and structural integrity of the valve body while minimizing defects.
Once the castings are cooled, they undergo machining to achieve precise dimensions and smooth surfaces. CNC machines or lathes are often used to create internal channels, threads, and connection points that ensure proper fit and functionality. Special attention is paid to the valve seat and sealing surfaces, as these areas directly affect performance and leak resistance.
After machining, components are cleaned, polished, and inspected for quality. Assembly follows, starting with the installation of internal parts such as the valve stem, ball, or disc, and seals or gaskets made from durable, water-resistant materials. The components are carefully aligned to guarantee smooth operation and leak-proof performance. Threaded or flanged ends are then attached to allow connection to piping systems.
The final stage involves rigorous testing, including pressure testing, leak detection, and functional operation checks. Only valves that pass these tests are packaged and prepared for distribution.
