MAINTENANCE
1) Stop the system and verify there is no pressure in the lter.
2) Collect the oil inside the lter with a suitable container.
3) Unscrew the bowl (1) and clean it.
4) Remove the dirty lter element (2).
N.B. The exhausted lter elements and the oil dirty lter
parts are classied “Dangerous waste material” and must
be disposed of according to the local laws, by authorized
Companies.
5) Check the lter element part number on the lter label or in
the ordering and option chart.
Use only original spare parts.
6) Lubricate the element o-ring gasket (3) with oil.
7) Insert the clean element into its seat with care.
8) Check the bowl o-ring condition (4) and lubricate with oil
If damaged, check the seal kit part number in the spare seal
kit table.
N.B. The anti-extrusion o-ring (5) must be positioned
downwards (under the gasket).
9) Screw the bowl (1) until it stops, with a tightening torque of
70 Nm + 5/0.
Accessories:
Clogging indicator (6).
If damaged, unscrew and replace it (check the part number in the
ordering and option chart).
Lubricate the o-ring gasket with oil and tighten until it stops, with a
tightening torque of 40 Nm +5/0.

PRESSURE DROP CURVES (Δp)
The “Assembly Pressure Drop (Δp)” is obtained by adding the
pressure drop values of the Filter Housing and of the Clean Filter
Element corresponding to the considered Flow Rate and it must be
lower than 120 kPa (1,2 bar). In any case this value should never
exceed 1/3 of the bypass valve setting.

CLEAN FILTER ELEMENT PRESSURE DROP WITH H+ MEDIA
(depending both on the internal diameter of the element and on the
lter media) - Recommended with no bypass option
PRESSURE DROP CURVES (Δp)
The “Assembly Pressure Drop (Δp)” is obtained by adding the
pressure drop values of the Filter Housing and of the Clean Filter
Element corresponding to the considered Flow Rate and it must be
lower than 120 kPa (1,2 bar). In any case this value should never
exceed 1/3 of the bypass valve setting.

BYPASS VALVE PRESSURE DROP
When selecting the lter size, these curves must be taken into account if it is foreseen that any ow peak is to be absorbed by the bypass
valve, it also must be of proper conguration to avoid pressure peaks. The valve pressure drop is directly proportional to uid specic gravity.
REVERSE FLOW VALVE
For hydraulic systems where reverse ow can occur, the pressure lters series FPB2+ and FPB3+ are available with a free reverse ow valve
allowing the uid to pass through the lter element in the normal direction and to bypass the lter element in the reverse direction (option “R”).
The reverse ow valve is available also with incorporated bypass valve for the normal ow direction, set at 6 bar (option “P”).
In normal ow conditions the whole ow pass through the lter element. In the option “P”, if the dierential pressure across the element
exceeds 6 bar the bypass is activated.
In reverse ow conditions the ow bypasses the lter element.
Pressure drop through the valve in the reverse direction:
0,4 bar at 100 L/min
0,6 bar at 200 L/min
0,8 bar at 300 L/min
All the curves have been obtained with mineral oil having a kinematic viscosity
30 cSt and specic gravity 0,86 kg/dm
3
; for uids with dierent features, please
consider the factors described in the rst part of this catalogue. All the curves
are obtained from test done at the UFI FILTERS HYDRAULICS Laboratory,
according to the specication ISO 3968:2005. In case of discrepancy, please
check the contamination level, viscosity and features of the uid in use.
