About valves; check (nonreturn) valves, for pipes, boiler shells, tanks, vats or the like

HS code 848130 covers a critical component in various industrial and commercial applications - check valves. These one-way valves play a crucial role in controlling the flow of liquids, gases, and other fluids, ensuring the safe and efficient operation of pipes, boilers, tanks, and other industrial equipment. As a key part of many supply chains, the production and trade of these valves have a significant impact on the broader economy, supporting a wide range of industries from manufacturing to construction and beyond.

Production process

The production of check valves typically involves a combination of metalworking, machining, and assembly processes. Manufacturers may start with raw materials such as steel, brass, or other metal alloys, which are then cut, shaped, and machined into the necessary valve components. These components are then assembled, often with the addition of seals, springs, and other functional parts, to create the final check valve product. Quality control and testing are essential steps to ensure the valves meet industry standards and specifications.

Production inputs

The main inputs required for the production of check valves include raw materials such as 720810 steel, 740311 copper, and other metal alloys. Manufacturers also rely on specialized machinery and tools for cutting, shaping, and assembling the valve components. Additionally, various seals, springs, and other hardware are necessary to complete the final valve assembly.

Production outputs

The primary output of HS code 848130 is check valves, which are used in a wide range of applications, including 841430 air or gas compressors, 841480 other air or gas compressors, and 841490 parts of air or gas compressors and fans; ventilating or recycling hoods incorporating a fan. These valves are essential components in the production and distribution of various fluids, gases, and other materials, supporting industries such as manufacturing, construction, and utilities.
