Rated flow stands for approximate flow rate when the pressure drop between inlet and outlet ports of the valve in fully opened condition becomes
0.3 MPa (44 PSI) maximum at fluid's specific gravity of 0.85 and kinematic viscosity of 20 mm2/s (98 SSU).
275
Hydraulic Fluids
Fluid Types
Any type of hydraulic fluids listed in the table below can be used.
Petroleum base oils
Use fluids equivalent to ISO VG 32 or VG 46.
Synthetic fluids
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.
Water containing fluids
Use water-glycol fluid.
Note: For use with hydraulic fluids other than those listed above, please consult your Yuken representatives in advance.
Recommended Viscosity and Oil Temperatures
Use hydraulic fluids which satisfy the recommended viscosity and oil temperatures given below.

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 µm or finer line filter.

Flow Controls
FLOW CONTROLS
Flow Control Valves / Flow Control and Check Valves
These valves are pressure and temperature compensating type valves and
maintain a constant flow rate independent of change in system pressure
(load) and temperature (viscosity of the fluid). They control flow rate of the
hydraulic circuit and eventually control speed of the actuator precisely.
Valves with an integral check valve allow a controlled flow and reverse free
flow. Repeated resetting can be made easily with a digital readout.

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.
FGM-10Y is special type sub-plate to be used with pipe flange. When
ordering FGM-10Y, specify pipe flange kit in addition to FGM-10Y
referring to F3 pipe flanges show on page 821.
Instructions
Min. required pressure difference
The minimum differential pressure between inlet and outlet port is required to obtain the optimum pressure
compensation. It varies according to the flow rate to be set. For details, please refer to the performance curves.
Free flow
Check valve pressure drops vary with flow rates. If models with check valves are used, see free flow pressure drop
characteristics.
Flow adjustment
[F*G-01]
Loosen the locking screw and turn the flow adjustment dial clockwise for increase, and anti-clockwise for decrease. The
dial makes about 4 revolutions from zero to full flow and the valve opening is indicated on the revolution indicator.
(Refer to characteristics of "Metred Flow vs. Dial Position").
After flow adjustments, tighten the locking screw.
[F*G-02, 03, 06, 10]
Loosen the locking screw and turn the flow adjustment handle clockwise for increase, and anti-clockwise for decrease.
Open condition is indicated in digital-scale in built-in revolution indicator (Refer to the characteristics of "Metred Flow
vs. Dial Position").
After flow adjustments, tighten the locking screw.
Line filter
To carry out flow adjustments by as small degree as 2 L/min (.53 U.S.GPM) or less, be sure to use a line filter of 10 µm
or finer and install it near the valve inlet.

FLOW CONTROLS
Pilot Operated Flow Control Valves / Pilot Operated Flow Control and Check Valves
Flow control of these valves is continuously
made by a hydraulically operated pilot
piston mechanism which controls opening
area of the orifice of the valve. With the use
of these valves, shockless operation either in
acceleratio or deceleration can be obtained.
With the compensator for the pressure and
temperature, stable flow control can be
obtained regardless of the changes in the
pressure (load) and temperature (oil
viscosity).

1. Both solenoid operated directional valve (DSG-01) and modular valve (MSW-01) can be used as a pilot valve.
If no pilot valve is required, there is no needs to specify the coil type and the electrical connection type of solenoid operated directional valve.
2. The coil types are same as those for DSG-01 Series solenoid operated directional valves. See solenoid ratings on page 345.
3. Pres. compensator stroke adjustment: Can reduce jumping at the start of the actuator.
In the table above, the symbols or numbers highlighted with shade represent the optional extras.
The valves with model number having such optional extras are handles as options, therefore,
please confirm the time of delivery with us before ordering.

While the solenoid operated directional valve off ( 4
shown left)
The flow rate is set by the minimum flow adjustment
screw and the actuator operates at the minimum
speed setting.
When the solenoid operated directional valve is
turned on ( 1 shown left)
The flow rate is shifted from minimum to maximum
and the actuator speed is also shifted likewise. The
switching time can be set by the pilot flow adjustment
dial 1 .
When the solenoid operated directional valve is
turned off ( 3 shown left)
The flow rate is shifted from maximum to minimum
and the actuator speed is also shifted likewise. The
switching time can be set by the pilot flow adjustment
dial 3 .
Tightening of flow adjustment screws and dials
To adjust flow rates, slacken the lock nut or the dial
setting screw. After adjustments, tighten the lock nut
or the dial.
Free flow
Check valve pressure drops vary with flow rates. If
models with check valves are used, see free flow
pressure drop characteristics.
Min. required pressure difference
The minimum differential pressure between inlet and
outlet port is required to obtain the optimum pressure
compensation. It varies according to the flow rate to
be set. For details, please refer to the performance
curves.
Line filter
To carry out flow adjustments by as small degree as 2
L/min (.53 U.S.GPM) or less, be sure to use a line filter
of 10 µm or finer and install it near the valve inlet.

FLOW CONTROLS
Restrictors / One Way Restrictors
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.

Deceleration Valves / Deceleration and Check Valves
These valves are available either with or without an integral check valve which allows free reverse flow. Flow rate
through the valve is regulated by the movement of the spool, which is operated by a cam. When the spool is
depressed, the flow is decreased in Normally Open type valves and increased in Normally Closed type valves. Their
principal use is to control the speed of actuators in machine tools and similar applications.

These valves are the combination of flow control valve, a deceleration valve and
a check valve and used mainly for controlling rapid traverse and feed cycles
machine tools. Switching from rapid traverse to feed is made by a cam
operation, and fine feed control is accomplished by dial rotation regardless of
pressure and oil temperature variation. Rapid return is free of cam actuation.

Instructions
Allowable pressures at controlled flow outlet
If internal drain types of UCF1G-01 or 03 or UCF2G-03
are used, use them in metre-out circuits in order to limit
the valve outlet pressure to the valves shown below.
In addition, external drain types can also be used in metrein circuits.

Minimum required pressure difference
The minimum pressure differential between inlet and
outlet port is required to obtain the optimum pressure
compensation. It varies accordingly to the flow rate to be
set. For details, refer to the performance curve.
Spool push down level
Limit the spool push down level within the allowable
maximum stroke range shown in the installation drawings.
Allowable drain port back pressure
Limit to 0.1 MPa (15 PSI).
In addition, connect the drain pipe independently and
directly to the tank. (This applies only to external drain
types.)
Flow adjustment
[UCF1G-01, UCF G-03]
Loosen the locking screw and turn the flow adjustment
dial clockwise for increase, and anti-clockwise for
decrease.
The dial makes about four revolutions from zero to
full flow and the valve opening is indicated on the
revolution indicator.
After flow adjustment, tighten the locking screw.
[UCF G-04]
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.
After flow adjustment, tighten the locking screw.
