The BS1868 ASTM A351 CF3M Swing Check Valve is a heavy-duty non-return valve designed for high-corrosion environments. The CF3M (316L equivalent) stainless steel body features low carbon content to prevent sensitization during welding. With an ASME Class 300 rating, it handles higher pressures than standard utility valves. The swing-type disc provides a full-flow path with minimal pressure drop, making it ideal for chemical, pharmaceutical, and offshore applications.
