The DCF Series is a robust Double Block & Bleed (DBB) floating ball valve with a modular construction. The valve features bi-directional sealing with C-RPTFE soft seats for maximum chemical compatibility combined with minimum coefficient of friction. It features double positive isolation with minimal external potential leakage points. This valve is suitable for flow measurement, sampling, chemical injection, and process isolation. The high-quality investment cast makes it a reliable solution for the toughest requirements.
