The history of plastic water valve manufacturing in China dates back several decades. Initially, metal valves dominated the industry due to their strength and durability. However, as the demand for cost-effective, lightweight, and corrosion-resistant products increased, plastic valves started gaining popularity. China, with its well-established manufacturing infrastructure and access to raw materials, quickly adapted to this shift. The transition from metal to plastic was driven by the need for better solutions for water distribution and management systems that could withstand environmental stresses while maintaining affordability.
