The Wide Caliber Wafer Dual Disc Check Valve from Zhewu is a high‑flow Check Valve with fluorine‑lined dual‑disc wafer‑type structure. This robust Industrial Check Valve can also be manufactured as a Stainless Steel Check Valve or Non Return Valve to meet different project demands. This fluorine‑lined wafer double‑disc check valve features fast opening‑closing speed and low water‑hammer effect. The fluorine‑lined material delivers excellent strong‑corrosion resistance. It is suitable for pipeline systems carrying highly corrosive media, especially for large‑flow working conditions in chemical and metallurgical industries.
