The BS1868 ASTM A351 CF8 Swing Check Valve is a standard industrial non-return valve designed to prevent backflow in stainless steel piping. The CF8 (304 equivalent) material provides excellent corrosion resistance for water, oil, and chemical services. Operating at 150lbs (Class 150), it features a bolted cover for easy internal maintenance. Its swing-type disc offers a clear, full-bore flow path, minimizing pressure loss and ensuring efficiency in low-pressure systems.
