Pentair Powder Butterfly Valves F250P/F251P Ski-Jump
Pentair Powder Butterfly Valves F250P/F251P Ski-Jump are used in powder conveying/transport applications. Our comprehensive valve line features both manual and pneumatic drive options, including lockable handles and vertical actuators.
Offering a comprehensive range of butterfly valves for a wide range of applications on powder conveying systems for the food, dairy, pharmaceutical, and beverage industries. The F250P/F251P Ski-Jump Valve features advanced butterfly valve seat technology based on many years development while working closely with powder handling specialists. As a result the valve provides optimized performance in this harsh abrasive environment.
The F250P/F251P Ski-Jump Valves are available in a number of executions, including wafer flanges, butt weld, RJT, clamp, and other end connections. The F250P/F251P Ski-Jump Valve is also available in a USDA compliant variation that meets the most stringent requirements for the U.S. dairy market. Pentair offers a variety of options that allow monitoring and control of the valves through a PLC control system via the Easymind control unit both standard and an IEC Ex version is available for Zone 22 installations.
