PVC Butterfly Valve

Priority on media compatibility: In strong acid and chloride ion environments, pitting may still occur in metal valves even if 316L stainless steel is used, while PVC butterfly valves can operate stably for a long time.

Life cycle cost: For low-pressure and non-high-temperature scenarios, the procurement and maintenance costs of PVC valves are 40% to 60% lower than those of metal valves.

Hygiene and cleanliness requirements: Food-grade PVC does not require electroplating or coating to avoid metal ion contamination of the fluid.

Advantages

Polyvinyl chloride (PVC) is a cost-effective engineering plastic. The butterfly valve body is manufactured by injection molding.PVC butterfly valves resistant to hydrochloric acid (≤30%), sulfuric acid (≤50%), sodium hydroxide (≤20%) and other media, with a corrosion rate of less than 0.1mm/year;

PVC butterfly valves also have Lightweight design, The density is only 1.38g/cm³, which is 1/5 of the weight of the same size stainless steel butterfly valve, reducing the pipeline support load; And Low friction coefficient, it surface smoothness Ra≤0.8μm, reducing fluid resistance and energy consumption by 10%~15%;

It also featured inInsulation and antistatic: volume resistivity＞1×10¹⁴Ω·cm, suitable for flammable and explosive environments (must comply with ATEX certification). Meanwhile, The operating temperature range of PVC butterfly valve is 0℃~60℃, short-term resistance to 70℃thermal shock, and long-term exposure to ultraviolet rays requires the addition of anti-aging agents.

Application

1.PVC butterfly valve canapplied in Chemical industry including electroplating liquid transportation, pickling wastewater neutralization treatment pipeline (DN50~DN300);

2.Water treatment system (sodium hypochlorite dosing pipeline in municipal sewage plant, seawater desalination pretreatment unit), And Food and pharmaceutical, such as pure water circulation system, CIP cleaning pipeline (FDA-certified PVC raw materials are required);

3.Construction and agriculture: irrigation pipeline network, swimming pool water circulation control valve.
