Valves; for oleohydraulic or pneumatic transmissions

HS v2022 Code: 848120

About valves; for oleohydraulic or pneumatic transmissions

HS code 848120 covers valves used in oleohydraulic or pneumatic transmission systems. These valves play a crucial role in the operation and control of hydraulic and pneumatic equipment, which are widely used across various industries, including manufacturing, construction, agriculture, and transportation. The demand for these valves is driven by the growing need for efficient and reliable power transmission systems, making this industry an integral part of the broader industrial machinery and equipment sector.

Production process

The production of valves for oleohydraulic or pneumatic transmissions typically involves several key steps. Manufacturers begin by selecting and sourcing the necessary raw materials, such as metals, polymers, and sealing components. These materials are then subjected to various machining, casting, or forging processes to shape the valve body, stem, and other critical components. Precision engineering techniques, including CNC machining and computer-aided design, are often employed to ensure the valves meet strict performance and quality standards. Finally, the assembled valves undergo rigorous testing and quality control measures before being packaged and distributed to customers.

Production inputs

The main inputs required for the production of HS code 848120 valves include metals (such as steel, brass, and aluminum), polymers (like rubber and plastics), and specialized components like seals, springs, and actuators. Additionally, manufacturers rely on advanced machinery and equipment, such as CNC machines, casting and forging equipment, and testing apparatus, to ensure the consistent quality and performance of the final products. The availability and cost of these raw materials and capital goods can significantly impact the overall production costs and competitiveness of this industry.

Production outputs

Valves classified under HS code 848120 are primarily used as components in oleohydraulic or pneumatic transmission systems, which are found in a wide range of industrial equipment and machinery. These valves are often consumed by manufacturers of 842123 Pumps; for liquid, whether or not fitted with a measuring device, 842129 Liquid elevators, and 842131 Air or vacuum pumps, as well as in the production of various 848410 Gaskets and similar joints of metal sheeting combined with other material or of two or more layers of metal. The demand for these valves is closely tied to the performance and growth of the broader industrial machinery and equipment sector.
