特點：

Maximum flow rates depend on operating conditions.  

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. 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.

Due caution must be paid to maintaining control over contamination of the hydraulic 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.  

簡介：

The shut-off type solenoid operated directional valves are poppet type 

solenoid operated two-way directional valves developed to meet 

the needs of this age such as energy and resources saving.

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.

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)] 

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

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. Use fluids equivalent to ISO VG32 or VG46.
