See the "Min. Adjustment Pressure" for the item marked .
These valves are flow control valves having the functions of metre-in type flow control and pressure control.
Inlet pressure is always maintained 0.6 MPa (87 PSI) higher than the load pressure.
In a conventional flow control method, power consumption is wasteful since the pump pressure goes up to the preset
system pressure regardless of the load pressure. While, the power saving valves control the pump pressure by maintaining
a differential pressure as little as 0.6 MPa (87 PSI) against the load pressure, thereby, the power can be remarkably saved.
Moreover, with lthe temperature compensator, a stable flow control can be made regardless of oil temperature.
Setting and repeat setting of flow can be made easily with an adjustment knob having digital scales.

Hydraulic Fluids / Instructions
Water containing fluids
Synthetic fluids
Petroleum base oils
Use water-glycol fluid.
Use phosphate ester or polyol ester fluid.When phosphate ester fluid is used,
prefix "F-" to the model number because the special seals (fluororubber) are required to be used.
Use fluids equivalent to ISO VG32 or VG46.

Fluid Types
Hydraulic Fluids
Any type of hydraulic fluids listed in the table below can be used.
Note: For use with hydraulic fluids other than those listed above, please consult your Yuken representatives in advance.
2
Viscosity ranging between 15 - 400 mm /s (77 - 1800 SSU).
Oil temperatures between -15/+70°C (5 - 158°F).
Use hydraulic fluids which satisfy the recommended viscosity and oil temperatures given above.
Due caution must be paid to maintaining control over contamination of the hydraulic fluids which may otherwise lead
to breakdowns and shorten the life of the valves. Please maintain the degree of contamination within NAS 1638-Grade
12. Use 25
μ
m or finer line filter.

Instructions
Mounting Bolts
Attachment
Sub-plate
Sub-plates are available. Specify the sub-plate model number from
the table above. When sub-plates are not used, the mounting surface
should have a good machined finish.
Loosen the locking screw and turn the flow adjustment
handle clockwise to increase, and anti-clockwise to
decrease. Open condition is indicated in digital-scale in
built-in revolution indicator (Refer to characteristics
of "Metred flow vs. Dial Position").
After flow adjustments, tighten the locking screw.
Pressure adjustment
To adjust the pressure, loosen the lock nut and turn the
pressure adjustment screw slowly clockwise to increase
pressures or anti-clockwise to decrease pressure. After
adjustments, do not forget to tighten the lock nut.
Drain port back pressure
Note that any drain port back pressure is added to the
minimum pressure.
Connect the drain port, preferably with its back pressure
minimized, directly to the oil tank.
Relief valve throughput
When the relief valve throughput is small with pressure
under control, the pressure setting may become unstable.
Thus, hold the rate above 10 L/min (2.6 U.S.GPM) for
nominal valve size 03 and 06 or above 15 L/min (4 U.S.
GPM) for nominal valve size 10.
Line filter
In case of controlling flow rate of less than 2 L/min (.53
U.S.GPM), be sure to use a line filter of 10
μ
m or finer
at the valve inlet.
EFBGM-10Y is special type sub-plates to be used with pipe flange.
When ordering EFBGM-10Y, specify pipe flange in addition to
EFBGM-10Y referring to F3 pipe flange catalogue (No. Pub. EC-
3001).

Note: When ordering the seals, please specify the seal kit number from the
table right.
When making replacement of seals, please do it
carefully after reading through the relevant
instructions in the Operator's Manual.

Petroleum base oils
Synthetic fluids
Water containing fluids
Use fluids equivalent to ISO VG 32 or VG 46.
Use phosphate ester or polyol ester fluid. When phosphate ester fluid is used, prefix "F-" to the
model number because the special seals (fluororubber) are required to be used.
Use water-glycol fluid.

This valve is used to regulate an actuator speed in a circuit where line pressure is almost steady and small fluctuation of
oil flow due to pressure changes is permitted. Integrated check valve allows reversed free flow from outlet to inlet port.
Pressure balanced construction provides less effort in adjustment at high pressure.
Hydraulic Fluids
Recommended Viscosity and Temperatures
2
Viscosity ranging between 15 - 400 mm /s (77 - 1800 SSU).
Oil temperatures between -15/+70°C (5 - 158°F).
Use hydraulic fluids which satisfy the recommended viscosity and oil temperatures given above.
Control of Contamination
Due caution must be paid to maintaining control over contamination of the hydraulic fluids which may otherwise lead
to breakdowns and shorten the life of the valves. Please maintain the degree of contamination within NAS 1638-Grade
12. Use 25
μ
m or finer line filter.

Fluid Types
Any type of hydraulic fluid listed in the table below can be used.
Note: For use with hydraulic fluids other than those listed above, please consult your Yuken representatives in advance.
