Models with AC Solenoids DSPG-01-C-?-20/2090
The location and the position of the cable departure can be changed. For details, see the cartridge type.
Models with DC Solenoids
two-way directional valves developed to meet the needs of this age such as energy and resources saving.
High response is provided by the poppet design. Smallest internal leakage
Internal leakage are very small, less than 5 drips per min., which is achieved by the poppet design.
fluids which may o therwise 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. Control of Contamination
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.
Maximum Flow Rate The zone under each shaded line denotes the flow rate ranges being free of trouble in changeover. 2
Typical Performance Characteristics at Viscosity 30 mm /s (141 SSU) [ISO VG 46 oils, 50°C(122 °F)]
Petroleum base oils
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
Shut-off Type Solenoid Operated Directional Valves DSPG-01
These ports (2) are not used. In addition, the body has the O-ring grooves and O-rings are included
in the body. The mounting dimensions conform to ISO 4401-AB-03-4-A. Ports A and B are used as ports "2"
and "1" respectively. O-rings for ports: SO-NB-P9
Fluid Types Hydraulic Fluids 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. Recommended Viscosity and Oil Temperatures
Use water-glycol fluids or W/O emulsion type fluids.
The shut-off type solenoid operated directional valves are poppet type solenoid operated
Two mounting types: cartridge and subplate Mounting dimensions for both types conform to ISO standard.
Water-proof type (conforming to JIS D 0203 Water Spray Test 32) is also available.
Cartridge Type / Sub-plate Mounting SOLENOID OPERATED DIRECTIONAL VALVES DSPC/DSPG-01/03(1/8, 3/8)
Maximum flow rates depend on operating conditions. For details,
Due caution must be paid to maintaining control over contamination of the hydraulic
