Pentair’s F250 powder valve with pneumatic actuator and Easymind control top features advanced butterfly valve seat technology. One of the main features of the valve, the deflection zone (ski-jump), minimizes direct impingement of high-velocity product particles on the sealing surfaces. The valves are available in a number of executions, including wafer flanges, butt weld, RJT, clamp and other end connections. Their unique polyurethane bushing reduces seat torque and maximizes seat life.
