FLW Product Lines We Repair
Our engineers are trained on the full FLW product range. Below are the major product families we service.
Proportional Directional Control Valves (NG6 & NG10)
FLW's flagship proportional spool-valve platform with integrated electronics for load-sensing and pressure-compensated flow control. Common faults include spool stiction, erratic position feedback, solenoid coil burnout, and onboard amplifier module failures affecting precision positioning in injection molding and metal fabrication.
Proportional Pressure Relief & Flow Control Modules
Compact FLW cartridge-style proportional reliefs and sequence valves with electric feedback and onboard electronics. Prone to leakage in spools, pressure transducer drift, and electronic amplifier module corrosion in humid textile-mill and food-processing environments.
Integrated Hydraulic Control Units (IHCU)
FLW's all-in-one hydraulic manifold combining proportional valves, pressure/flow sensors, and onboard PLC-interface electronics in a single ductile-iron casting. Frequent failures include manifold-mounted PCB connector corrosion, sensor signal loss, and solenoid winding insulation breakdown.
Solenoid Coil Assemblies & Spool Position Transducers
FLW solenoid electromagnetic coils and LVDT position feedback transducers for proportional valves. High-failure-rate components subject to voltage spikes, moisture ingress in condensation-prone plants, and mechanical shock from system pressure surges.
Amplifier & Control Electronic Modules
FLW stand-alone amplifier cards, on-board proportional valve driver modules, and CAN/Profibus communication interface boards. Electronics degrade under thermal cycling, salt-spray exposure in coastal plants, and electrical noise from unshielded power lines in Indian manufacturing facilities.
Pressure & Flow Transducers (Analog & Digital)
FLW integrated and standalone pressure, flow-rate, and temperature sensors with 4-20mA, PWM, or CANopen outputs. Signal degradation, sensor zero-drift, and connector corrosion are prevalent in high-vibration automotive assembly lines and steel-rolling mill environments.

Common FLW Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in FLW equipment arriving at our workshop.
- ✓Proportional Solenoid Coil Open-Circuit Winding — FLW solenoid coils fail due to insulation breakdown from moisture ingress, thermal cycling in seasonal Indian climates, or voltage transients from uncontrolled system pressure spikes. Winding resistance exceeds specification or drops to near-zero indicating shorted turns.
- ✓Spool Position Feedback (LVDT) Signal Loss or Drift — FLW LVDT transducers suffer environmental corrosion, connector pin oxidation in humid textile mills, or mechanical spool binding that prevents proper core movement. Signal output drifts out of 4-20mA window, causing closed-loop control instability and erratic valve positioning.
- ✓Onboard Proportional Valve Amplifier Module Thermal Shutdown — FLW proportional valve driver electronics overheat due to high-ambient factory temperatures, inadequate manifold cooling, or sustained high-current solenoid activation in continuous-duty applications. Amplifier enters thermal protection, cutting solenoid drive and freezing valve spool mid-stroke.
- ✓Manifold-Mounted PCB Connector Corrosion & Signal Interruption — FLW integrated hydraulic control units (IHCU) exhibit connector pin corrosion in coastal plants, humid food-processing facilities, and condensation-prone textile mills. Moisture-laden air infiltrates unsealed connector backshells, oxidizing gold-plated contacts and causing intermittent signal dropout.
- ✓Pressure & Flow Transducer Zero-Drift or Non-Linearity — FLW pressure/flow sensors drift due to diaphragm fatigue, piezo-element aging, or compensation-circuit capacitor value drift. Sensor reads high/low across operating range, causing proportional valve over-/under-correction and system oscillation or loss of feedback control.
- ✓Proportional Valve Spool Stiction & Erratic Position Response — FLW proportional valve spools bind due to varnish buildup from oxidized hydraulic oil, contamination from worn pump/motor components, or corrosion in high-moisture environments. Spool stiction causes sluggish or inconsistent movement and jerky closed-loop control in injection molding and automotive assembly processes.

Frequently Asked Questions — FLW Repairs
Do you repair FLW equipment anywhere in India?+
Yes. Synchronics repairs the complete FLW proportional valve, hydraulic control unit, transducer, and solenoid portfolio. We operate PAN India door-pickup service from Mumbai, Pune, Aurangabad, Delhi, Gurgaon, Hyderabad, Bangalore, Chennai, Coimbatore, Ahmedabad, Surat, and all tier-2 manufacturing cities. Repairs are performed in our main facility in Vadodara, Gujarat. Express turnaround available for critical automotive and textile machinery downtime.
What is the typical repair turnaround for FLW proportional valve electronics?+
FLW proportional valve onboard amplifier modules and LVDT transducers are diagnosed and repaired in 3-5 business days if components are in stock. Solenoid coil replacements, connector refurbishment, and sensor re-calibration take 4-6 days. Critical priority repairs (automotive OEMs, textile mills on production hold) are expedited to 24-48 hours. Synchronics maintains a buffer stock of common FLW replacement parts to minimize turnaround.
Can you repair FLW IHCU (Integrated Hydraulic Control Units) with manifold-mounted electronics?+
Yes. FLW IHCU manifolds are high-complexity integrated systems with proportional valves, sensors, and PLC-interface PCBs cast into a single ductile-iron block. Synchronics performs full diagnostics on IHCU units, identifies faulty proportional driver modules, replaces corroded onboard connectors, re-seals sensor ports, and calibrates all transducers. Manifold integrity testing (leak test at operating pressure) is performed before return. Typical IHCU repair window is 5-7 days.
Do you stock FLW solenoid coils and LVDT transducers for immediate replacement?+
Yes. Synchronics maintains inventory of FLW solenoid coils (24DC/48AC NG6 & NG10 spools), LVDT position feedback transducers, pressure transducers (0-350bar range), and amplifier driver modules. For non-stocked variants, we source directly from FLW Germany distributor partners and have parts available within 4-5 working days. Emergency same-day solenoid replacements are coordinated for active Synchronics repair jobs.
What causes FLW proportional valve spool stiction in Indian manufacturing plants?+
FLW proportional valve stiction is prevalent in Indian automotive assembly lines, textile mills, and food-processing plants due to oxidized hydraulic oil, high moisture environments, and pump-component wear particles. Spools become sticky, reducing dynamic response and causing jerky proportional control. Synchronics performs ultrasonic cleaning of FLW valve cavity blocks and spool bores, renews worn sleeves, and recommends fluid flushing to ISO 4406 16/14/11. This resolves 95% of stiction issues without component replacement.
How do I send my FLW 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 FLW 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 FLW 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 FLW 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.
