Selection of Control Valve in Paper Industry Design

Paper production process is divided into two parts: pulping and papermaking.

The pulping process is to prepare pulp which can be made of wood and other raw materials rich in fibers through the preparation, cooking, washing and screening, bleaching and other processes. In the paper-making process, the pulp delivered by the pulping department will be used to produce finished paper after pulping, conveying, pressing, drying and coiling. In addition, the alkali recovery Department recovers the alkali liquor from the black liquor discharged after pulping for reuse. Wastewater treatment department is to treat paper-making wastewater and make it meet the relevant national discharge standards.

The control of throttle valve is indispensable in all the above papermaking processes.
