Fluorine-lined Flanged Swing Check Valve

Strong corrosive pipes need a check valve. This stops backflow from damaging pumps and equipment. Our Fluorine Lined Flanged Swing Check Valve has a carbon steel shell with a full F46 lining. The disc and seat also have a fluorine plastic lining. So the corrosive media never touches the metal. The model H44F46-16C means check valve, flange, swing type, F46 lining, PN16, and cast steel. The disc swings open when media flows forward. When flow reverses, the disc closes by its own weight and back pressure. It responds fast and reliably. Compared to normal check valves, the flow path is smoother. The flow resistance is lower.

Suhao has mature fluorine lining processes. We use high-temperature compression molding. The lining sticks tightly to the body. There are no bubbles or pinholes. It can handle hydrochloric acid, sulfuric acid, and nitric acid for a long time. Each Fluorine Lined Flanged Swing Check Valve gets a spark test before shipping. This makes sure there are no defects in the lining. You can buy this with our fluorine lined ball valves and fluorine lined globe valves. This gives you a full set of anti-corrosion pipe solutions. Our fluorine products are already used in many large chlor-alkali plants and fine chemical projects.
