Check valves
Series FPV plastic flap check valves are suitable for use where backflow could cause damage to pumps, filters or process equipment and operate without requiring adjustments or settings. Line pressure moves the solid plastic flap off the elastomer seat, opening the valve. When inlet flow stops, back pressure moves the flap back onto the seat, stopping flow.
