In the paper and pulp manufacturing industry, control valves play a crucial role. These valves are responsible for regulating and controlling the flow of various fluids, thereby ensuring the smooth progress of the entire production process. Handling high-density fluids means dealing with corrosion and erosion, especially in critical sections such as effluent discharge, black liquor, and wastewater treatment, where the performance requirements for valves are extremely high.
In the papermaking process, wastewater is an inevitable by-product. In the effluent discharge section, C-type valves are commonly used. These valves have a simple structure, are easy to operate, and provide good sealing, effectively preventing wastewater leakage into the external environment.
In the black liquor section, which involves high-temperature, highly corrosive liquids such as sulfuric acid, sodium sulfite, lime, and sodium sulfide used in the pulp preparation stage, there is a need for specialized acid and alkali-resistant valves. Sun Yeh ceramic-lined control valves use high-performance ceramic materials as linings, which not only withstand high temperatures but also offer excellent resistance to acids and alkalis. Therefore, neither strong acids nor strong alkalis can corrode these valves. Moreover, due to the high hardness of the ceramic material, these valves also have good wear resistance and can maintain stable performance over long-term use.
In the wastewater treatment section, 900T type control valves are needed. These valves are typically used to adjust the flow and pressure during the wastewater treatment process. Due to their outstanding performance and reliability, Sun Yeh ceramic-lined control valves have become the preferred choice for this type of valve. They can easily withstand the weight of wastewater and ensure stable and controllable flow during the treatment process.
Overall, Sun Yeh ceramic-lined control valves are widely used in the paper and pulp industry. They meet the demands of various complex conditions, and due to their excellent corrosion resistance, wear resistance, and relatively long service life, these valves can help enterprises reduce maintenance costs and improve production efficiency. Thus, it can be said that Sun Yeh ceramic-lined control valves are a wise choice for the paper and pulp manufacturing industry.
