Imported plastic valves refer to industrial pipeline control components with high-molecular plastics (such as PVC, PP, PVDF, PTFE, etc.) as the core valve body material. Their core characteristics are "strong corrosion resistance + lightweight + low cost + hygienic and environmentally friendly." Industrial certifications include ISO 9001, CE, FDA (food grade), and NSF/ANSI 61 (drinking water safety). The applicable temperature range is -40℃ to 150℃ (high-temperature PVDF models can reach 180℃), the pressure range is Class 15 to Class 100 (0.1-1.6MPa), the nominal diameter is DN15 to DN300, and the sealing rating reaches ANSI Class IV to V. They are suitable for acid, alkali, salt solutions, and low-viscosity corrosive media applications.
Widely used in chemical acid and alkali pipelines, electroplating wastewater treatment, food and beverage cleaning pipelines, electronic ultrapure water transportation and other fields, with the characteristics of "corrosion resistant and rust-free + easy installation + low maintenance cost", it solves the problem of metal valves being prone to corrosion and failure in strong corrosive media, and is a core control component in low-pressure and strong corrosion scenarios.
