Plastic valves are devices made from plastic materials (such as polypropylene, polyvinyl chloride, polyethylene, etc.) that are widely used in various systems requiring fluid flow control. Compared to traditional metal valves, plastic valves offer advantages such as being lightweight, corrosion-resistant, oxidation-resistant, having insulating properties, low noise, cost-effectiveness, and recyclability, which makes them widely utilized across multiple industries.
