Pilot Operated Hydraulic Directional Valves (DHG)

HIGH FLOW

○ The high flow rate 63 lpm (16.6 gpm) of the DSG-(N)-01 valves corresponds to conventional 03 valves.

○ DSG-(N)-03 is capable of controlling oil flow up to 120 lpm (31.7 gpm)

○ DSHG-(N)-04 are capable of controlling oil flow up to 300 lpm (79.3 gpm)

○ DSHG-(N)-06 are capable of controlling oil flow up to 500 lpm (132 gpm)

And DSHG-(N)-10 are capable of controlling oil flow up to 1000 lpm (291 gpm)

[Flow rate is a little different between different spool type.]

HIGH PRESSURE

The DSG-(N)-01/03 solenoid valves, DSHG-(N)-04/06/10 Max operating pressure up to 315 bar(4500 PSI).

LONG SERVICE LIFE

○ Durable Life: Durability to 50 million spool shifts.(Average)

○ Life Of Sealing : No oil leaks due to use of no-dynamic seals.

POWERFUL QUIET WET ARMATURE SOLENOID

Totally enclosed molded coil. Specially treated pressure resistant inner tube(SUS304). High grade steel cored(C2503) coil with

wet solenoid. All moving parts are immersed in operating oil and muffled to provide low noise operation.

NO OIL LEAKAGE

Special design of over-ride pins and seals prevent oil leakage.

HIGH BACKPRESSURE ALLOWED IN TANK (DRAIN) LINE

○ The DSG-(N)-01/03 can be used with back pressure up to 160 bars(2300 PSI) on the tank port “T”.

○ DSHG-(N)-04/06/10 permissible backpressure, internal drain 160 bars(2300 PSI), and 210 bar (3000 PSI) for external drain type. Pipe the return back to tank below the oil level.

INDICATOR LIGHTS (LEDS)

○ Solenoid indicator lights are standard, all DSG-01/03 (terminal box type), DSG-N-01/03 (DIN type) with all voltages, ensuring

    easy testing and maintenance at a glance.

○ DIN connector meet CE, IP 65, DIN 40050, ISO 6952 water proof standard.

    (AC: Red led., DC: Yellow led.)

COIL

○ Insulation high voltage test: 1500 V/min. (1800 V/sec.)

○ Double insulation wiring, hermetically sealed for moisture-resistance. Insulation class : H

○ Maximum allowable coil temperature: +150C (+300F)

○ Do not exceed permissible voltage range of the coil used.

○ Do not supply electric power to the AC solenoid unless the coil is mounted to the valve.

○ DIN type coil with 360 possible orientation.

○ No-spring type (DSHG-2N*-04/06/10) one of the coil should be energized continuously to avoid malfunction.

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

HI-TENSILE CAST IRON (FC 30)

Bodies are of high tensile cast iron with large shell cored passages. Spool bores are precision honed with accurately machined

land locations.
