AFS Product Lines We Repair
Our engineers are trained on the full AFS product range. Below are the major product families we service.
AFS Proportional Valve Controllers
Electronic control units for proportional spool valves, managing pressure, flow, and directional control in hydraulic circuits. Common issues include amplifier saturation, feedback signal drift, and solenoid coil failures due to moisture ingress in humid Indian climates.
AFS Hydraulic Amplifier Modules
Standalone signal conditioning and amplification units for proportional valve systems. Failures typically stem from power supply ripple, environmental contamination, and connector corrosion in coastal or high-dust industrial facilities.
AFS Integrated Flow Management Systems
Compact closed-loop flow regulation systems combining electronics, solenoids, and feedback transducers. Common faults include transducer signal loss, valve spool stiction after extended idle periods, and firmware obsolescence in legacy installations.
AFS Pressure & Temperature Monitoring Units
Auxiliary sensor interface modules providing real-time diagnostics for proportional systems. Typical failures include 4-20mA loop faults, thermistor failures, and microcontroller reset cycles under voltage transient stress.
AFS Valve Spool Feedback Transducers
LVDT and inductive position sensors providing real-time spool displacement feedback to proportional controllers. Prone to mechanical wear, cable abrasion damage, and offset drift from thermal cycling in outdoor hydraulic cabinets.

Common AFS Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in AFS equipment arriving at our workshop.
- ✓Proportional valve solenoid coil open circuit — Moisture ingress through connector seals combined with thermal cycling causes insulation breakdown in solenoid windings, particularly common in Indian textile mills and humid coastal manufacturing environments. AFS solenoids lack secondary conformal coating on legacy models.
- ✓Proportional controller amplifier saturation or clipping — Industrial power supply noise, inadequate input filter capacitance, or misaligned feedback transducers cause the AFS proportional amplifier to saturate, limiting valve modulation range. Occurs frequently in Indian plants with aging three-phase electrical infrastructure and high switching-frequency motor loads.
- ✓Feedback transducer signal loss or drift — AFS LVDT and inductive sensors suffer cable insulation damage from hydraulic fluid contact, mechanical abrasion against valve manifolds, or offset calibration drift over 3-5 years in thermal cycling conditions typical of Indian textile dyeing and chemical dosing plants.
- ✓4-20mA control signal loop fault or impedance mismatch — Long cable runs in Indian industrial facilities introduce loop resistance exceeding AFS amplifier input specifications, or PLC/controller output impedance mismatch causes signal attenuation. Common in retrofit installations using existing plant wiring with inadequate gauge conductors.
- ✓Microcontroller watchdog reset or firmware corruption — Power supply transients from Indian industrial grid switching, brown-out events, or inadequate decoupling capacitor aging cause the AFS controller microcontroller to experience watchdog timer resets. Legacy AFS firmware may have checksum validation bugs triggered by power interruptions.
- ✓Valve spool stiction after extended idle or seasonal shutdown — Hydraulic fluid oxidation, viscosity change in high ambient temperatures (45C+ in Indian summers), or microscopic surface corrosion on AFS valve spools causes stiction and sluggish proportional response. Common after monsoon periods or multi-month seasonal shutdowns in food processing and textile facilities.

Frequently Asked Questions — AFS Repairs
Do you repair AFS equipment anywhere in India?+
Yes. Synchronics repairs the full AFS proportional valve control range, hydraulic amplifiers, flow management systems, and feedback transducers. We offer PAN India door-to-door pickup from Mumbai, Delhi, Pune, Bangalore, Chennai, Hyderabad, Ahmedabad, Kolkata, and all tier-2 industrial cities. Equipment is transported to our 45000 sq ft Vadodara facility for complete diagnostics, repair, calibration, and functional testing under AFS factory standards.
What is the typical repair turnaround for AFS proportional valve controllers?+
Standard AFS controller repair turnaround is 5-7 working days after receipt, including full diagnostics, component replacement, recalibration to AFS specifications, and bench testing under simulated load conditions. We offer expedited 48-hour turnaround for critical production equipment. Indian shipping typically adds 2-3 days depending on your location; we coordinate pickup and delivery to minimize downtime.
Can Synchronics recalibrate AFS LVDT feedback transducers on-site?+
Yes, our service engineers are equipped with portable AFS-compatible precision test benches for on-site LVDT offset calibration, linearity verification, and sensitivity tuning. We can recalibrate transducers mounted on existing proportional valves without requiring complete system disassembly. We also provide remote calibration support via phone/video if you prefer factory-level accuracy validation in Vadodara.
Do you stock genuine AFS spare parts and replacement components?+
Synchronics maintains stock of genuine AFS solenoid coils, proportional amplifier modules, LVDT feedback sensors, connector assemblies, and decoupling capacitor kits. We have direct sourcing agreements with AFS authorized distributors and maintain emergency procurement channels for obsolete legacy components. Our parts warehouse in Vadodara ships replacement items across India within 24-48 hours.
What testing do you perform on repaired AFS equipment before shipping back?+
Every repaired AFS device undergoes comprehensive functional testing including proportional modulation response curves, frequency response analysis, signal noise floor verification, temperature stability cycling (0C to 60C), humidity chamber exposure, and full 4-20mA loop validation. We generate detailed test reports documenting all parameters against AFS original specifications. Equipment is bench-tested with actual hydraulic proportional valves under load to ensure real-world performance before shipment.
How do I send my AFS 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 AFS 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 AFS 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 AFS 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.
