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.
SPOOLS
Spools are hardened alloy steel(SCM21), precision ground and incorporate balancing grooves. All spools are interchangeable
with valve body simplifying maintenance. Many options in spool type selection.
3 STANDARD ELECTRICAL CONNECTIONS TYPE, VARIOUS COIL VOLTAGES
There are 3 types (DIN, Terminal Box, SWP) for standard electrical connection and variety of AC,DC & RAC coil voltages. Coil
voltages. AC:AC100V/AC110V/AC200V/AC220V/AC240V (50/60HZ) DC:DC12/24/36/48.
HYDRAULIC SHOCKLESS TYPE (S)- LOW NOISE TYPE
The DC/RAC type solenoid valves with a cushion device, results in a smooth com- mutation from a position to another position
(smooth start and stop performance). This will greatly reduce the noise which comes from changing over and vibrating pipes.
The optional stroke limiter (RW/RA/RB) can be 1/4., 1/3., 1/2 micro adjustments search for the best soft smooth cushion. When
the stroke limiter is screwed in, the main spool stroke becomes shorter and flow rate becomes lower.The max adjustment range
details as follows:
DSG-(N)-01-DC/RAC: max. 1.4 mm
DSG-(N)-03-DC/RAC: max. 2.2 mm
DSHG-(N)-04-AC/DC/RAC: max. 7 mm
DSHG-(N)-06-AC/DC/RAC: max. 12 mm
SPECIAL TYPE, (VOLTAGES) ARE AVAILABLE.
(A) Shockless + shifting time adjustable. (B) Stroke limiter adjustable.(RA/RB/RW types)
(C) Lead wire type (SWP connector terminals) for marine, mobile parts.
(D) Explosion proof (flame proof) type. (E) Surgeless (Surge Killer) type.
(F) Sparkless (Spark Killer) type. (G) Water proof type. (H) Vibration proof type.
(I) AC24., DC 14.50., DC28., DC36., DC 48., DC110 (J) Viton seals were available.
Consult local agent for details.
ASSEMBLY INSTALLATION
The no-spring valves (DSHG-2N-04/06/10TYPE) shall mounted with longitudinal axis horizontal as they work under impulse.
Spring centered (3C*) .spring offset (2B*) and detented (2D*) valves have no orientation limitation. The DSG-(N)-01/03 & DSHG-(N)-04/06/10 mounting surface dimensions conform to ISO 4401, Hydraulic fluid power-Four-port directional control valves-
Mounting surface. The installation surface should be finer than 6.3 S.
SUBPLATE & MANIFOLDS
Comprehensive range of sub-plates, multi-station manifolds and stackable modules.
MOUNTING BOLTS + ACCESSORIES.
Hexagonal socket head cap screw (Metric or American fixing bolts), and DIN connector + led as standard with no extra cost.
