PP Ball Valve

Xinda Chemical is a professional manufacturer of PP ball valves which is designed for the control of corrosive media pipelines.Ball valve body using polypropylene (PP) or PPH material injection molding, acid, alkali, salt and a variety of chemical solvent has good resistance, fundamentally avoid metal valve corrosion problems.The internal sphere rotates 90 degrees to quickly open and close, the operation is very convenient, and the flow channel is smooth, the fluid resistance is small, which helps to reduce the energy consumption of the system.

It can not only be used for manual operation, but also be equipped with electric or pneumatic actuators for automatic control.Therefore, it is widely used in the chemical and pharmaceutical industry reaction process, environmental protection water treatment system drug dosing, food and beverage health pipeline and all kinds of corrosive fluid delivery scene in the laboratory.

Specifications and Characteristics

Key points for selection and maintenance

When selecting PP ball valve, the core of selection is to accurately match the size (DN) and working pressure (PN) of the pipeline, and confirm the applicability of the sealing material (such as FKM, EPDM) according to the corrosion and temperature of the medium, which directly determines the sealing reliability and service life of the valve.

Daily installation and maintenance is the key to ensure its performance.The installation should ensure that the bolts are aligned and tightened evenly.Check the sealing status of valve stem and interface regularly, open and close smoothly during operation. If there is poor opening and closing or internal leakage in the later stage, it is usually a signal of wear of vulnerable parts such as the internal sealing ring. Timely replacement can restore performance and effectively extend the overall service life of the valve.
