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.
Use phosphate ester or polyol ester fluid. When phosphate ester fluid is used, prefix "F-" to Synthetic fluids 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.
Name Viscosity Temperature

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.
276 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 FGM-10Y is special type sub-plate to be used with pipe flange. When the table above. When sub-plates are not used, the mounting surface ordering FGM-10Y, specify pipe flange kit in addition to FGM-10Y should have a good machined finish. 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.

288 Flow Control Valves / Flow Control and Check Valves 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). D

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.

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.

Throttle Modules / Throttle and Check Modules 309 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.

Deceleration Valves / Deceleration and Check Valves 317 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.
