Rated flow is the approximate flow rate, when there is a free flow pressure drop of maximum 0.3 MPa (44 PSI), the fluid has a specific
gravity of 0.85 and a kinematic viscosity of 20 m m2/s (98 SSU), and the cracking pressure is 0.04 MPa (6 PSI).

Right Angle Check Valves

■ Pilot Operated Check Valves

These check valves allow flow in one direction and prevent flow in the reverse direction, until operated by pilot pressure
to allow free reverse flow. The specified cracking pressure is required to open the valve to allow free flow direction.

Operation of internal and external drain types DR
P2 P1
When the outlet side P1 is directly connected to the tank in reversed
free flow (Fig. a), the internal drain type is normally used. When P1
the back pressure is applied to the outlet side P1 (Fig. b), be sure
to use the external drain type. (Fig.a) (Fig.b)

Minimum pilot pressure characteristics WARNING
That depends on the pressure of the inlet side P2 in the reversed
free flow. The machinery, if misused due to failure to observe

type valves with 50 design valves.

In 20 design valve with cracking pressure of 0.035 MPa (5 PSI)
(Code "5"), for closing the valve completely and certainly, it was
necessar y to introduc e the pressurize d oil into the drain port to
push down the piston compulsory.
While in 50 design valve with cracking pressure of 0.04 MPa (6
PSI) (Code "6"), it has such structure that the valve can be closed
completely and certainly without introducing the pressurized oil
into the drain port. On the contrary , what is worse is that if the
pressurized oil is introduced into the drain port, the oil acts towards
the direction o f opening the valve, which i s very dangerous and
has to be absolutely avoided. Therefore, please do not supply any
pressurized oil into the drain port in case of using 50 design valve.

Hydraulic Fluids

1. Type of Fluids
Any type of hydraulic fluid, listed in the table below can be used.

Type of Fluids Remarks
Petroleum Base Oils Use fluids equivalent to ISO VG32 or VG46.

Synthetic Fluids 1) Use phosphate ester or polyol ester type. When phosphate ester
Water Containing Fluids type fluid is to be used, prefix “F-” to the model number
because a special seal (fluororubber) will be used.

Use water-glycol fluids or W/O emulsion type fluids.

Notes 1: Not applicable with G-DSG and G-DSHG series valves. 06 10
06X 10X
2: For two types of manually operated directional valves, DMT- and DMT- , only petroleum base oils
and polyol ester type fluids are available.

3: Water-glycol fluids cannot be used for two types of solenoid operated poppet type two-way valves; CDST-

03✻ and CDSG-03 types. E

4: For use with hydraulic fluids other than those listed above, please consult your Yuken representatives is

advance.

2. Recommended Viscosity and Oil Temperatures
Use hydraulic fluids which satisfy the both recommended viscosity and oil temperatures given in the table below.

3. Control of Contamination

Due caution must be paid to maintaining control over contamination of the hydraulic fluids which may otherwise lead
to breakdowns and shorter the life of the valve. Please maintain the degree of contamination within NAS 1638-Grade
12. Use 25 µm or finer line filter (In case of DSG-005 series Solenoid Operated Directional Valves, NAS1638-Grade
11. Use 20 µm or finer line filter).

One of two solenoids should be energised continuously to avoid malfunction.

2. On double solenoid valves do not energise both at the same time as it will result in coils burning out.

● Pilot Drain Port for Solenoid Controlled Pilot Operated Valve Directional Valves
Avoid connecting the valve pilot drain port to a line with possible surge pressure.

● Shockless Type lbf. N except for DSG-005
In order to benefit from a shockless operation, it is necessary to fill the 30 150 DSG-005

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
Water containing fluids the model number because the special seals (fluororubber) are required to be used.

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

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.

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 D

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.

298 Pilot Operated Flow Control Valves / Pilot Operated Flow Control and Check Valves

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.
