FELLTRON Product Lines We Repair
Our engineers are trained on the full FELLTRON product range. Below are the major product families we service.
Proportional Directional Control Valves (PDCV)
Felltron's core product family for flow direction and pressure modulation in hydraulic circuits. Common faults include solenoid coil burnout, internal spool stiction, pressure transducer drift, and internal leakage. These valves are critical in injection moulding, hydraulic presses, and machine tool applications.
Proportional Pressure Relief Valves (PPRV)
Felltron pressure relief systems for load-holding and overpressure protection. Failures often stem from pilot stage leakage, main spool corrosion, electrical signal loss, or contaminated pilot oil. Used extensively in die-casting and forging equipment across India.
Electro-Hydraulic Actuator Control Units (EHACU)
Felltron integrated controllers for proportional valve command, sensor feedback, and system diagnostics. Typical faults include relay card failures, feedback transducer malfunction, software corruption, and power supply damage. Essential for automated textile machinery and packaging lines.
Spool Actuator and Solenoid Assemblies (SASA)
Felltron proportional solenoid coil assemblies for valve actuation and directional control. Prone to solenoid coil open circuits, armature stiction due to contamination, hysteresis drift, and connector corrosion. Commonly replaced components in field repairs.
Proportional Pump Controller Modules (PPCM)
Felltron controllers for variable displacement pump pressure and flow compensation. Failures include feedback sensor failures, control electronics failure, and load-sensing signal loss. Critical for energy-efficient hydraulic systems in Indian manufacturing.
Hydraulic Servo Valve and Pilot Amplifier Units (HSV-PAU)
Felltron servo control systems for high-precision motion control and load management. Typical issues include amplifier oscillation, pressure transducer calibration drift, feedback loop instability, and internal blockage. Used in precision hydraulic presses and machine tools.

Common FELLTRON Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in FELLTRON equipment arriving at our workshop.
- ✓Solenoid coil open circuit or burnout — Felltron proportional solenoid coils fail due to overvoltage spikes from unfiltered power supplies, moisture ingress through damaged connectors, or extended energisation causing insulation degradation. In Indian factories with poor power stability, voltage transients frequently damage 24V coils.
- ✓Spool stiction and sluggish response — Hydraulic contamination (ISO cleanliness > 19/17/14) causes internal spool binding in Felltron directional valves. Corrosion from water ingress and bacterial growth in oil tanks accelerates spool friction. Common in factories without proper oil maintenance.
- ✓Proportional pressure transducer zero drift and reading errors — Felltron integrated pressure transducers (0-400 bar range) drift due to thermal cycling, long-term sensor fatigue, or oil ingress into electrical connectors. Moisture in pilot oil lines causes signal instability and false fault codes in EHACU controllers.
- ✓Pilot oil filter blockage and slow pilot pressure build-up — Felltron proportional valves use fine mesh pilot filters (10 micron) that block rapidly in contaminated systems. Varnish deposits from oxidised hydraulic oil and particulate accumulation restrict pilot flow, preventing proportional valve response.
- ✓Electronic control card relay and output stage failure — Felltron EHACU relay cards suffer from contact erosion after 100,000+ switching cycles, inducing coil creep from vibration in production machinery, and solder joint fatigue from thermal shock. Power surges from unshielded motors cause output transistor failure.
- ✓Feedback signal loss and proportional valve hunting — Felltron pressure transducers and spool position feedback sensors lose signal due to corroded solder joints, broken internal wires, or EMI interference from VFDs and servo drives. Cable shield degradation is common in high-temperature injection moulding facilities.

Frequently Asked Questions — FELLTRON Repairs
Do you repair Felltron equipment anywhere in India?+
Yes. Synchronics repairs the full Felltron proportional valve and electro-hydraulic control range — directional control valves, pressure relief systems, servo actuators, pump controllers, and EHACU units. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bangalore, Kolkata, and all tier-2 cities. All repairs are completed at our main facility in Vadodara, Gujarat with 48-72 hour turnaround for most faults.
What is the typical repair cost for a Felltron proportional directional control valve?+
Felltron PDCV repair costs depend on fault severity and model size. Solenoid coil replacement runs INR 4,000-8,000. Full internal overhaul with spool refinishing and seal replacement costs INR 8,000-15,000 for WD-04/06 models, and INR 12,000-20,000 for larger WD-10/16 units. Synchronics provides free diagnostics and written quotes before repair. Genuine Felltron spare parts and labour are included.
How do I identify which Felltron proportional valve I have if the nameplate is damaged?+
Synchronics can identify Felltron valves from serial numbers, cartridge dimensions, solenoid coil specifications, and porting configuration. Photo our technicians from your valve cartridge, pilot section dimensions, and coil connector type. We maintain a complete Felltron model database and can cross-reference your equipment even with partial information. Contact us via email with images for fast identification.
Can Synchronics repair Felltron EHACU electronic control cards if they show fault codes?+
Yes. Synchronics troubleshoots Felltron EHACU fault codes (E01-E12 series) by testing power supply voltages, relay switching, proportional output signals, and feedback signal conditioning. We repair shorted output stages, replace failed relays and capacitors, and reprogram or replace defective microcontroller modules. Most electronic faults are resolved within 2-3 days. We provide fault code documentation and repair reports.
What preventive maintenance does Synchronics recommend for Felltron proportional valves in Indian factories?+
Synchronics recommends quarterly pilot filter changes (10 micron), hydraulic oil sampling (ISO 16/14/11 target cleanliness), transducer calibration verification annually, solenoid coil insulation resistance testing (minimum 10 megohm @ 500V), and connector moisture checks quarterly in humid or coastal facilities. We offer preventive maintenance contracts for manufacturing plants with multiple Felltron systems. Regular servicing extends valve life by 40-60% and prevents catastrophic failures in production.
How do I send my FELLTRON 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 FELLTRON 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 FELLTRON 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 FELLTRON 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.
