Advantages
Corrosion Resistance: Plastic materials are highly resistant to corrosion from a wide variety of chemicals, making plastic ball valves suitable for handling aggressive fluids that would quickly corrode metal valves.
Lightweight: They are much lighter than metal valves, which simplifies installation, reduces transportation costs, and makes them easier to handle in general.
Cost - Effective: Plastic ball valves are often more affordable than their metal counterparts, especially for applications where high - end metal alloys are not required.
Chemical Compatibility: Different types of plastics can be selected based on the specific chemical properties of the fluid being handled, ensuring excellent compatibility and preventing chemical reactions that could damage the valve or contaminate the fluid.
Low Maintenance: Due to their resistance to corrosion and wear, plastic ball valves typically require less maintenance compared to metal valves, resulting in lower long - term operating costs.
Applications
Chemical Industry: Used for handling acids, alkalis, solvents, and other corrosive chemicals in chemical processing plants.
Food and Beverage Industry: Ideal for applications where hygiene and non - contamination are critical, such as in the production of food, beverages, and dairy products.
Water Treatment: Employed in water purification, sewage treatment, and irrigation systems for controlling the flow of water and chemicals used in the treatment processes.
Pharmaceutical Industry: Ensures the integrity of pharmaceutical fluids during production, storage, and transportation, as plastic materials do not react with most pharmaceutical substances.
Swimming Pool and Spa Systems: Commonly used to control the flow of water, chemicals, and sanitizers in swimming pools and spas due to their resistance to chlorine and other pool chemicals
