REVERSE FLOW VALVE NORMAL FLOW REVERSE FLOW For hydraulic systems where reverse flow can occurr, the pressure filters series FPB+ and FPB3+ are available with a free reverse flow valve allowing the fluid to pass through the filter element in the normal direction and to bypass the filter element in the reverse direction (option R ). The reverse flow valve is available also with incorporated bypass valve for the normal flow direction, set at 6 bar (option P ). In normal flow conditions the whole flow pass through the filter element. In the option P, if the differential pressure across the element exceeds 6 bar the bypass is activated. In reverse flow conditions the flow bypasses the filter element. Pressure drop through the valve in the reverse direction: 0,4 bar at L/min 0,6 bar at L/min 0,8 bar at 300 L/min
PB CLOGGING INDICATOR A visual or visual-electrical differential indicator is available as an option and allows monitoring of the element conditions, giving an exact indication of the right time to replace the element. FILTER HOUSING The head by high performance cast iron and the bowl by extruded steel ensure the best fatigue resistance to the working pressures. FILTER ELEMENT The filter element is manufactured with filter medias selected in the UFI laboratory and mechanically supported to maintain the highest performance even at high differential pressures. SEAL GUARANTEED A perfect O-ring seal is always ensured as it is not dependent on the tightening torque applied to the bowl. EASY MAINTENANCE The hexagon end of the bowl allows for easy maintenance by using a simple hexagon wrench. CLOGGING INDICATOR For further technical informations and other options see page 8-83.
