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.

Flow Control and Check Valves ...... Page 2

These valves are pressure and temperature compen-

sating 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.

Pilot Operated Flow Control

and Check Valves ......................... Page 14

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 acceleration 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).

Hydraulic Fluids

Recommended Viscosity and Oil 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 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.

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 flange kits Catalogue (No. Pub. EC-3001).

Instructions

The minimum differential pressure between inlet and outlet port is required to obtain the optimum pressure com-

pensation. It varies according to the flow rate to be set. For details, please refer to the performance curves.

Min. required pressure difference

Check valve pressure drops vary with flow rates. If models with check valves are used, see free flow pressure drop

characteristics.

Free flow

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.

Flow adjustment

[F

∗

G-01]

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

After flow adjustments, tighten the locking screw.

[F

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

Either solenoid operated directional valve (DSG-01) or 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.

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.

FGM-10Y is special type sub-plates to be used with pipe flange. When

ordering FGM-10Y, specify the pipe flange kit in addition to FGM-10Y

referring to F3 pipe flange kits Catalogue (No. Pub. EC-3001).

Instructions

While the solenoid operated directional valve on ( shown below), the flow rate is at the level set by the maximum

flow adjustment screw and the actuator operates at the maximum speed setting. Turning the adjustment screw clock-

wise causes the flow rate to decrease.

While the solenoid operated directional valve off ( shown below), the flow rate is set by the minimum flow adjust-

ment screw and the actuator operates at the minimum speed setting. Turning the adjustment screw clockwise causes

the flow rate to increase.

When the solenoid operated directional valve is turned on ( shown below), 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 (for acceleration). Turning the adjustment dial clockwise causes the pilot flow rate to decrease.

When the solenoid operated directional valve is turned off ( shown below), 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 (for deceleration). Turning the adjustment dial clockwise causes the pilot flow rate to decrease.

Control patterns and flow rate adjustment

The minimum differential pressure between inlet and outlet port is required to obtain the optimum pressure com-

pensation. It varies according to the flow rate to be set. For details, please refer to the performance curves.

Min. required pressure difference

Check valve pressure drops vary with flow rates. If models with check valves are used, see free flow pressure drop

characteristics.

Free flow

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

μ

m or finer and install it near the valve inlet.

Line filter

To adjust flow rates, slacken the lock nut or the dial setting screw. After adjustments, tighten the lock nut or the dial.
