Our larger FullFloXF 2-way, 3-way and check valves provide higher flow rates and produce much lower water pressure drop. These valves are ideal for diverting, shutoff, or mixing applications. The polytetrafluoroethylene (PTFE) composite diverter seal requires no lubrication. Field-adjustable stops ensure precise positioning while simplifying use, and the extra wide diverter offers superior sealing when used with actuators. The check valves have a gray flapper that makes it easy to see when the valve is open or closed.
