Who is the best in domestic plastic valves?
Thread Content
Which plastic valve is the best in China? It’s mainly the diaphragm valve. Resistant to hydrochloric acid, hypochlorous acid, wet chlorine gas, and chlorine water. Imported PVDF valves are too expensive, and there are also restrictions on them!
It seems that all valves of this type are manufactured in Ningbo!
For critical areas, it is recommended to use products from Asahi Organic; they are more expensive, but they hold up well over time
