HYDRECO Product Lines We Repair
Our engineers are trained on the full HYDRECO product range. Below are the major product families we service.
Proportional Directional Control Valves
HYDRECO NG10 and NG16 proportional directional spool valves with integrated electronics for flow control and pressure compensation. Common issues include spool stiction due to contamination, solenoid coil burnout, and feedback transducer signal loss affecting valve response.
Servo-Proportional Controllers
Digital and analogue servo-proportional control units managing multiple valve functions simultaneously. Repair focus includes PCB damage from power surges, signal conditioning circuit faults, and firmware corruption in networked systems.
Pressure Transducers and Feedback Sensors
4-20mA and 0-10V pressure transducers used in HYDRECO systems for real-time feedback and load sensing. Common faults include connector corrosion, bridge circuit imbalance, and zero/span drift due to thermal stress in high-temperature hydraulic environments.
Hydraulic Power Units with Control Electronics
Compact and modular HPU systems integrating pump motors, manifold blocks, and electronic control cabinets. Repair addresses motor soft-starter failures, control valve solenoid burnouts, and sensor interface PCB issues common in Indian textile and packaging plants.
Electro-Hydraulic Proportional Pumps
Variable displacement proportional pump units with electronic swashplate control and pressure relief integration. Failure modes include swashplate actuator solenoid failures, electrical position feedback loss, and control signal contamination affecting system stability.
Integrated Hydraulic Automation Modules
HYDRECO modular systems combining proportional valves, PLC interfaces, and real-time diagnostics for automated material handling and press control. Frequent repairs include Ethernet/Profibus gateway failures, analogue input card burnout, and sensor calibration drift.

Common HYDRECO Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in HYDRECO equipment arriving at our workshop.
- ✓Proportional solenoid coil open circuit failure — Repeated thermal cycling and moisture ingress in humid Indian industrial environments cause insulation breakdown in HYDRECO solenoid windings, particularly in textile mills and automotive paint shops with high ambient humidity.
- ✓Pressure transducer 4-20mA signal loss — Connector corrosion and oxidation at pressure port leads, common in HYDRECO PTG and PTH series deployed in coolant-rich environments. Intermittent signal dropout occurs before complete failure, affecting proportional valve feedback loop stability.
- ✓Proportional valve spool stiction and sluggish response — Hydraulic fluid contamination and micro-sludge accumulation on HYDRECO spool surfaces reduce dynamic response and cause hunting. This is prevalent in Indian plants with inadequate oil filtering and extended maintenance intervals.
- ✓Servo-proportional controller PCB relay chattering — Weak relay contacts and poor solder joints on HYDRECO HPC-N series control boards fail under switching loads, especially in high-frequency proportional valve applications common in automotive press lines.
- ✓Hydraulic power unit soft-starter intermittent motor cut-off — Soft-starter thyristor gate drive signal loss in HYDRECO HPU controllers causes random motor shutdown. Ground loop issues and poor power supply decoupling in dense Indian manufacturing floors introduce noise into control circuits.
- ✓Proportional valve position feedback linearity drift — Thermal compensation circuits in HYDRECO servo-proportional controllers drift due to aging resistor networks and capacitor leakage, reducing control accuracy. Indian plants with wide ambient temperature swings (25°C to 50°C) experience significant null offset errors.

Frequently Asked Questions — HYDRECO Repairs
Do you repair HYDRECO equipment anywhere in India?+
Yes. Synchronics is an authorised service centre for HYDRECO hydraulic electronics across India. We repair proportional valve controllers, servo-proportional systems, pressure transducers, and hydraulic power unit electronics. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bangalore, Kolkata, and all major industrial cities. Equipment is transported safely to our Vadodara, Gujarat facility for testing and repair, with regular courier updates provided.
What HYDRECO proportional valve fault codes do you diagnose?+
Synchronics uses genuine HYDRECO diagnostic tools to read fault codes from HPC-N and DPC series controllers — including solenoid drive failures (E01, E02), pressure transducer signal loss (E10, E11), spool position feedback errors (E20, E21), and power supply faults (E30). We cross-reference codes with HYDRECO technical documentation and perform root cause analysis on faulty PCBs using oscilloscope and multimeter testing.
How long does HYDRECO proportional valve controller repair take?+
Standard HYDRECO servo-proportional controller repair takes 5-7 working days for diagnostics, component replacement, and factory calibration. Urgent repairs with expedited component sourcing can be completed in 3-4 days. We test all repairs under simulated proportional load using precision test benches before shipping. Express courier return is available for critical plant downtime situations across India.
Can you repair HYDRECO pressure transducers and recalibrate them?+
Yes. Synchronics recalibrates HYDRECO PTG and PTH series pressure transducers against certified deadweight testers, ensuring NIST-traceable accuracy. We repair open circuits in 4-20mA signal conditioning circuits, replace failed bridge elements, and test sensor response across the full pressure range. Recalibrated transducers are supplied with calibration certificates and can be pressure-tested to 110% of maximum rated pressure before return.
What is Synchronics experience with HYDRECO hydraulic power units in Indian textile mills?+
Synchronics has repaired HYDRECO HPU systems in 150+ Indian textile mills across Tamil Nadu, Gujarat, and Maharashtra. Common repairs include proportional valve solenoid replacement, soft-starter thyristor repair, and hydraulic fluid contamination diagnostics. Our engineers understand Indian mill hydraulic standards and the challenges of extended shift operation in high-humidity weaving environments. We provide extended warranty on HPU repairs and recommend preventive maintenance schedules tailored to Indian mill conditions.
How do I send my HYDRECO 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 HYDRECO 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 HYDRECO 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 HYDRECO 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.
