valve operated with an electric signal via solenoid.  Because these are of poppet type,
the internal leakage is quite small and there is no worry about hydraulic lock.
Japanese Standard "JIS  European Design Standard N. American Design Standard Socket Head Cap Screws (2pcs.)
Solenoid Operated Poppet Type Two-Way Valves CDST/CDSC/CDSG-03(03W)
CDS?-03? has been model-changed (design 20 to design 21).  Specifications and Characteristics
There are no changes in the specifications and characteristics of the valves themselves. Solenoid Ratings
Interchangeability in Installation AC Solenoids Most items of mounting are interchangeable
except the dimensions as shown below.  In addition, the size of the spanner ( core end faces)
for locking the CDSC cartridges has been changed to 15-19 mm across flats.
Fluid Types Hydraulic Fluids Any type of hydraulic fluids listed in the table below can be used.
Mounting Bolts Mounting bolt in the table below is attached only for Gasket mounting type valve (CDSG-03).
Water-glycol fluids cannot be used for CDST-03/03W and CDSG-03 valves.
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 1 2.  Use 25 μm or finer line filter.
Use fluids equivalent to ISO VG 32 or VG46. Use phosphate ester or polyol ester fluid.
 When phosphate ester fluid is used, prefix "F-" to  the model number because the special
DC/R Type Solenoids Most items of mounting are interchangeable except the dimensions as shown below.
 The solenoid shape changed from c ircular to hexagonal. No change in the size
15 mm of the spanner for locking cartridges.
These valves are used for opening/closing the oil path by having the poppet
For use with hydraulic fluids other than those listed above, please consult your
seals (fluororubber) are required to be used. Use water-glycol fluids or W/O emulsion type fluids.
Interchangeability between Old and New Design Because of solenoid assembly improvements,
Yuken representatives in advance. 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. Recommended Viscosity and Oil Temperatures
