HACOBA Product Lines We Repair
Our engineers are trained on the full HACOBA product range. Below are the major product families we service.
HACOBA Proportional Directional Control Valves (NG10 / NG16)
Spool-type proportional valves with integrated electronics for precise flow and pressure modulation. Common issues include solenoid coil burn-out, LVDT position sensor drift, and contaminated spool stiction in Indian dusty environments.
HACOBA Pressure Relief and Pilot-Operated Valve Systems
Cartridge and subplate-mounted relief valves with proportional pilot control. Frequent faults include pilot seal leakage, poppet micro-chipping from hydraulic fluid contamination, and proportional solenoid hysteresis.
HACOBA Electronic Control Modules (ECM) and Amplifier Cards
Dedicated electronics for proportional valve command and feedback signal conditioning. Typical failures: capacitor failure in humid climates, relay chatter, and CAN bus communication loss in industrial settings.
HACOBA Flow Control and Needle Valve Assemblies
Precision micro-flow regulators used in metering applications. Common defects: needle seat erosion from abrasive particles, seal degradation under sustained pressure, and solenoid armature stiction.
HACOBA Integrated Valve Manifold Blocks (Subplates)
Custom ductile iron manifold blocks with cavity porting for proportional and ON-OFF valve integration. Repair challenges include internal cavity corrosion, seal groove damage, and cavity pressure drop mapping.
HACOBA LVDT Linear Position Transducers and Feedback Sensors
Inductive displacement transducers for spool position feedback in proportional systems. Frequent issues: cable break at connector, core rod corrosion, and signal drift due to temperature swings in uncontrolled factory environments.

Common HACOBA Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in HACOBA equipment arriving at our workshop.
- ✓HACOBA solenoid coil open circuit or megohm drift — Insulation degradation from moisture ingress, thermal cycling in hot stamping and die-casting plants, or contaminated cooling air in textile machinery. HACOBA solenoids are sealed but subject to condensation in tropical Indian climates and seasonal humidity swings.
- ✓Proportional spool valve stiction and sluggish response — Hydraulic fluid contamination (ISO > 19/17/14) causes varnish buildup on spool edges and bore walls. Indian plants often run mineral oils without adequate filtration; HACOBA precision fits (0.5-1 micron clearance) are especially vulnerable to particulate bridging.
- ✓LVDT position sensor signal drift and non-linearity — Temperature-dependent sensor drift in unshielded cable runs near hot hydraulic manifolds; electromagnetic interference from adjacent PLC power supplies; or mechanical stress on transducer body from vibration in packing and textile machinery.
- ✓Pilot relief cartridge poppet micro-damage and internal leakage — Sudden pressure spikes (water hammer, sudden load shedding) cause poppet chatter and micro-chipping. Abrasive particle impact during transient pressure events degrades the poppet sealing face, worsening under oscillating load cycles typical of injection moulding and servo-hydraulic test rigs.
- ✓ECM amplifier relay chatter and CAN bus communication failure — Supply voltage ripple, EMI from variable frequency drives in adjacent machinery, or loose connector pins corroded by salt spray (coastal Indian plants). HACOBA ECM CAN interface is sensitive to 48V supply noise above 0.5V peak-to-peak.
- ✓Manifold block internal cavity corrosion and micro-porosity leakage — Hydraulic fluid moisture contamination or use of incompatible fluid types corrodes ductile iron cavity walls. Some Indian reconditioners use low-grade casting iron; microscopic porosity allows slow internal seepage, especially under high pressure cyclic duty (automotive stamping lines).

Frequently Asked Questions — HACOBA Repairs
Do you repair HACOBA equipment anywhere in India?+
Yes. Synchronics repairs the full HACOBA proportional valve and hydraulic electronics product range — directional control valves, relief systems, ECM amplifiers, and LVDT feedback transducers. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bangalore, Kolkata, and all other cities. Repairs are completed at our 180+ engineer facility in Vadodara, Gujarat with 7-10 day turnaround for most units.
What is the typical turnaround time and cost for HACOBA proportional valve repair?+
Standard HACOBA proportional valve repair (solenoid replacement, spool polishing, electronics module diagnostics) typically takes 7-10 working days. Cost ranges from INR 12,000 to 45,000 depending on valve size (NG10 vs NG16) and extent of damage. Synchronics provides upfront diagnostics and quotation before proceeding. We offer 24-month repair warranty with spare parts availability through HACOBA's Europe supply chain.
What HACOBA fault codes can you diagnose and repair?+
Synchronics diagnostics cover HACOBA ECM error codes including solenoid open/short, LVDT signal out-of-range, supply voltage anomaly, CAN communication timeout, and relay fault states. We use HACOBA proprietary diagnostic software (where available) and perform bench functional testing to isolate faults. Most electronic module faults are corrected via relay replacement, capacitor refresh, or firmware reset. For persistent CAN bus errors, shielded cable upgrade or node replacement is often necessary.
Can you source genuine HACOBA spare parts and do you offer OEM warranty?+
Yes. Synchronics maintains relationships with HACOBA and authorized European distributors to source genuine OEM solenoid coils, seal kits, LVDT transducers, and electronic modules. All repaired units are tested with genuine HACOBA spares and backed by 24-month warranty. For critical automotive or aerospace applications requiring full traceability, we provide HACOBA certification of repair and spare part origin documentation.
Is HACOBA equipment used in Indian manufacturing and are your engineers trained on HACOBA systems?+
HACOBA proportional and directional control valves are widely used in Indian Tier-1 automotive suppliers, textile mills, injection moulding facilities, and heavy equipment manufacturers. Synchronics engineers are trained on HACOBA hydraulic principles, proportional solenoid operation, spool valve dynamics, and ECM electronics. We hold reference documentation for HACOBA NG10 and NG16 valve families and have repaired hundreds of units across Indian automotive and manufacturing sectors.
How do I send my HACOBA unit for repair?+
Pack the unit securely and courier it to our Vadodara workshop. Include a note with the fault description and your contact details. We will log it into our system and WhatsApp you a job number within 24 hours of receipt. Doorstep pickup is available in Vadodara, Ahmedabad, Surat, Mumbai, and Pune.
What is the cost of repairing a HACOBA drive or PLC?+
Repair cost depends on the model and the fault. We offer a free diagnosis — once we identify the fault, we provide a fixed quotation before proceeding. Typical repairs cost 20–40% of the new unit price. We will never repair without your approval.
What warranty do you provide on HACOBA repairs?+
All repaired units carry a 6-month comprehensive warranty covering the same fault and related issues. If the fault recurs within the warranty period, we repair it free of cost.
Do you provide a no-fix, no-fee guarantee?+
Yes. If we cannot repair your HACOBA unit after diagnosis, you pay only the diagnosis fee (₹500–₹1,500 depending on the product). The unit is returned to you at no additional charge.
