Low Noise Type Solenoid Controlled Relief Valves
The low-noise solenoid controlled relief valve is a combination of a low-noise type pilot operated relief valve and a
solenoid operated directional valve. It is used for no-load pump operation by using electric signals or, together with a
remote control relief valve, for two or three pressure control of the hydraulic system.

Specifications
Models with vent restrictor are applicable only for the vent type 2B3A and 2B3B. For details, see page 231.
Use high venting pressure types to reduce response time from unloading to onloading.
The vent types are the same as for the conventional type solenoid controlled relief valves. For the details of the vent types, see
page 221.
The coil codes are the same as for solenoid operated directional valve DSG-01 valve. See the solenoid ratings on
page 345.
Model Number Designation
For relief valves, low-noise type pilot operated relief valves are used.
For minimum adjustment pressures and other characteristics, see
page 218.
(Option-
Omit
if not
required)
The coil type numbers in the shaded column are handled as optional extras.
In case these coils are required to be chosen, please confirm the time of
delivery with us before ordering.

Attachment
Mounting Bolts
The type with a vent restrictor has a vent restrictor in vent types 2B3A and 2B3B added between a relief valve and a
solenoid operated directional valve. It prevents shock to the main circuit by gradually lowering the venting pressure
in the shift from the setting pressure to unloading.
Unloading pressures are the same as without a vent restrictor.
b
b
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.
The sub-plates are those for pilot operated relief valves. For dimensions, see
page 213.
If a remote control relief valve is used in the vent circuit, see page 203. In addition, if the internal volume of the vent
line is too large, chattering is likely to occur. Thus, as far as possible reduce the inside diametre and the length of the
pipe.
To adjust the pressure, loosen the lock nut and turn the handle slowly clockwise for higher pressures or anti-clock-
wise for lower pressures. After adjustments, do not forget to tighten the lock nut.
Piping of the tank line should not be connected to any tank line of the other valves, but connected directly to the
reservoir.
Pressure is limited by collars fitted. If a working pressure cannot be attained, remove some collars. One collar is
equivalent to 10 MPa (1450 PSI).
With a small flow, the setting pressure may be unstable. Use models numbered 03 and 06 with a flow rate above
5 L/min (1.3 U.S. GPM) and model 10 with 8 L/min (2.1 U.S. GPM).
Interchangeability in Installation between Old and New Design.
Design 53 valve is one on which DSG-01, design 70 is mounted as a pilot valve. It is interchangeable with old design
(design 52) with respect to specifications, exterior shape and mounting dimensions.
