Duplomatic Industrial Hydraulic Equipment & Systems
Engineered international procurement of genuine Duplomatic (Daikin Group) industrial hydraulic valves, proportional controls, variable vane and gear pumps, tie-rod cylinders, and turnkey hydraulic power units for machine tools, stamping presses, die-casting machinery, and metallurgy. Supported by certified spare parts and factory seal kits.
Duplomatic Product Lines & Hydraulic Component Series
Full spectrum of high-performance industrial hydraulic solutions: directional spool valves, proportional servo controls, variable displacement pumps, ISO cylinders, and custom hydraulic power packs.
Duplomatic DS3 & DS5 Directional Control Solenoid Valves
Engineered supply of Duplomatic DS3 (CETOP 03 / NG6) and DS5 (CETOP 05 / NG10) direct and electro-hydraulically operated directional spool valves designed for industrial machine tools, injection molding presses, metallurgical mills, and automated production machinery.
Valves mount on standard subplates conforming to ISO 4401 specifications, delivering dependable switching of hydraulic circuits at operating pressures up to 350 bar and flow rates reaching 100–150 l/min.
Wet-pin DC and AC solenoids feature rotatable coils sealed to IP65 with DIN 43650 Hirschmann connectors. We supply the comprehensive range of spool configurations with spring centering or detent holding, soft-shift orifice plugs, and manual overrides.
Supplying Duplomatic high-response proportional directional valves including direct operated DSE3/DSE5 units and pilot-operated two-stage DXE3J/DXE5J series featuring on-board digital electronics (OBE) and LVDT spool position feedback.
The series delivers continuous precision modulation of hydraulic velocity and cylinder movement according to analog (±10 V, 4–20 mA) or digital bus signals.
Widely deployed on CNC machining axes, hydraulic stamping presses, and dynamic testing fixtures, these valves guarantee hysteresis below 1.5%, exceptional flow linearity, and rapid step response times across wide operating temperature envelopes.
Duplomatic Pressure Relief, Reducing & Modular Pilot Check Valves
Procuring complete lines of Duplomatic pressure and sandwich control valves, including CR and CRQ direct and balanced pilot relief valves (adjustable up to 350 bar), PR and PRM pressure reducing valves for secondary circuit stabilization, and MVPP modular pilot-operated check valves conforming to CETOP 03.
Sandwich plate architecture underneath directional spools eliminates external interconnecting pipework, minimizing leakage points. MVPP lock valves feature precision ground poppet seats that ensure zero static leakage and reliable cylinder positioning under external loads upon pump shutoff.
Delivering Duplomatic industrial variable displacement vane pumps from the PVP series (up to 160 bar, displacements 16–73 cm³/rev) and heavy-duty PVD line (up to 210 bar, displacements 28–100 cm³/rev).
Pumps integrate direct mechanical and pilot-operated hydraulic pressure compensators that automatically modulate displacement based on circuit demand.
Upon reaching preset pressure, pump delivery drops to near zero, maintaining holding pressure with minimal energy consumption and eliminating hydraulic fluid overheating while preserving ultra-low acoustic emissions below 68 dBA.
Duplomatic GP Series External Gear Hydraulic Pumps
Supplying Duplomatic external gear pumps spanning GP1, GP2, and GP3 displacement groups from 1.3 to 87 cm³/rev with continuous pressure ratings up to 280 bar.
Manufactured with extruded high-strength aluminum alloy bodies, cast iron end plates, and hydrostatically balanced floating bush compensation, they maintain volumetric efficiency exceeding 95% across broad temperature and speed ranges.
Available with cylindrical keyed, 1:8 tapered, and DIN/SAE splined drive shafts alongside European 4-bolt and SAE oval mounting flanges.
Duplomatic HC2 Tie-Rod Hydraulic Cylinders (ISO 6020/2)
Procuring Duplomatic HC2 double-acting heavy industrial tie-rod hydraulic cylinders fully conforming to ISO 6020/2 and DIN 24554 standards.
Rated for continuous pressures of 160 bar with test pressures up to 250 bar, they power CNC machine tools, die-casting machinery, and automated assembly fixtures.
Featuring precision honed cylinder barrels, hard chrome-plated high-tensile steel rods, low-friction polyurethane seals, and adjustable progressive end-of-stroke cushioning, these cylinders deliver endurance exceeding 10 million cycles under heavy industrial duty.
Duplomatic HC3 Compact Block Hydraulic Cylinders
Supplying Duplomatic HC3 compact short-stroke block cylinders engineered with solid monolithic steel bodies for machine clamping jigs, metal stamping dies, plastic injection molds, and tooling fixtures.
These compact actuators generate extreme clamping forces in confined spaces and withstand operating pressures up to 250 bar (peaks to 320 bar). Hydraulic fluid connections are accommodated via standard BSP threaded ports or manifold manifold o-ring subplate drilling for direct embedded integration.
Duplomatic Hydraulic Power Units & Custom Manifold Systems
Engineering and delivery of complete Duplomatic hydraulic power units (HPUs) and custom manifold blocks built on PVP/PVD vane or GP gear pump configurations with reservoir capacities ranging from 25 to 1,000 liters.
Power packs integrate monolithic hydraulic manifolds, CETOP modular directional and pressure stacks, air/oil heat exchangers, fine pressure filtration, and continuous fluid condition monitoring. Systems are delivered fully assembled, pressure-tested, and ready for immediate plant integration.
Duplomatic EDM-M & EDC-1 Digital Electronic Drivers
Delivering Duplomatic EDM-M (DIN-rail mount) and EDC-1 (direct solenoid plug mount) digital electronic amplifiers engineered for driving open-loop and closed-loop proportional hydraulic valves.
Powered by 24 V DC supplies, they synthesize closed-loop PWM output currents with dynamic coil temperature resistance compensation. Parametric calibration via RS232 software interfaces enables precise tuning of acceleration/deceleration ramps, deadband offsets, and output gain profiles.
Supplying Duplomatic FPM high-pressure in-line filters (rated to 420 bar, flow to 450 l/min, inorganic microfiber cartridges with 3, 5, 10, or 25 micron absolute ratings) and PTH stainless-steel piezoresistive pressure transducers (ranges up to 600 bar, analog 0–10 V or 4–20 mA outputs).
These condition components safeguard precision servo hydraulics against particulate contamination and provide real-time pressure diagnostics to plant automation networks.
To determine the exact Duplomatic hydraulic configuration for machine modernization or replacement duty, our engineering specialists evaluate critical process parameters: rated and peak system pressures, required continuous flow rates in liters per minute, circuit switching sequences, hydraulic fluid viscosity profiles, and acoustic sound emission limits. Based on operating duty cycles, our engineers calculate nominal port sizes (CETOP 02, 03, 05, 07, 08), determine direct solenoid vs. electro-hydraulic pilot actuation, select spool spring centering characteristics, and evaluate requirements for stroke throttling damping plugs. For retrofit projects upgrading legacy hydraulic drives, custom manifold transition subplates are engineered to mount modern CETOP valves without costly modifications to permanent plant pipework. This ensures exceptional energy efficiency, dependable operation, and prolonged component lifespan across intensive manufacturing cycles.
Service Lifecycle & OEM Wear Parts Supply
Ensuring continuous reliable performance of Duplomatic hydraulic systems requires scheduled fluid cleanliness monitoring and proactive replacement of routine wear parts: encapsulated AC/DC solenoid coils, dynamic rod seals, NBR and FPM o-rings, wet armature guide tubes, FPM high-pressure microglass filter elements, and HC2 cylinder seal packs. We supply genuine factory maintenance kits featuring matched guide bushings, calibrated springs, and pre-formed elastomer seals that restore original factory tolerances and response dynamics. Parts are matched directly against complete alphanumeric model strings to ensure zero dimensional discrepancy. Proactive seal and cartridge replacement prevents internal pressure decay, cavitation, fluid overheating, and unscheduled production interruptions.
International Procurement & Supply Terms
Delivery of genuine Duplomatic hydraulic equipment, valves, pumps, cylinders, and spare parts is executed under international commercial supply contracts accompanied by conformity certificates, inspection datasheets, and official export documentation. We do not claim exclusive territorial distributorship and operate through verified independent global supply chains. Commercial pricing, fabrication lead times, and freight schedules are determined on a per-project quotation basis.
