The papermaking/printing industry is an important part of the national economy, covering two core areas: papermaking and printing. The papermaking industry is an industrial sector that manufactures various types of paper and paperboard. It includes the pulp manufacturing industry that produces pulp using raw materials such as wood, reeds, sugar cane residue, straw, wheat straw, cotton stalks, hemp fibers, cotton, etc., the paper and paperboard manufacturing industry, and the processing paper manufacturing industry that produces coated, varnished, glazed, laminated, and other processed papers and type paper plates for printing. Papermaking is one of the four major inventions of China. The printing industry is an industry system that transfers graphic and textual information onto the substrate using printing plates or digital technology, covering areas such as publications, packaging decoration, commercial printing, etc., and is widely used in cultural dissemination, product value addition, and brand services, forming a complete industrial chain covering raw material supply, production manufacturing, and application services.
In the papermaking and printing industries, BAHE valves play a crucial role. They control the flow and pressure of fluids (such as pulp, water, chemicals, ink, etc.) to ensure the smooth progress of the production process, while also guaranteeing production safety and product quality.
