NORVIN Repair Services India

Yes. Synchronics is the authorised repair partner for NORVIN proportional directional valves, relief valves, flow control systems, and electronic amplifier cards across India. We offer door-to-door pickup and delivery from all major metros — Mumbai, Delhi, Bangalore, Chennai, Hyderabad, Pune, Ahmedabad, and 200+ smaller industrial towns. Repairs are completed in our Vadodara, Gujarat facility within 5-7 working days. We hold spares inventory for solenoid coils, proportional amplifier cards, and pressure transducers.

For standard NORVIN proportional valve repairs (spool cleaning, solenoid coil replacement, pressure transducer calibration), turnaround is 5-7 working days from receipt. Complex assemblies requiring electronics module troubleshooting or pilot stage rebuilding may take 10-12 days. Synchronics offers express 48-hour repair for critical production downtime emergencies on selected NORVIN products. Loaners are available for mission-critical systems.

Yes. Our engineers are certified in NORVIN ECM (Electronic Control Module) repair, including proportional amplifier card diagnostics, CAN-bus gateway testing, and digital I/O interface troubleshooting. We repair onboard 4-channel and 8-channel proportional controllers, replace degraded components like power output transistors and op-amp stages, and re-flash control firmware if required. All repairs include full functional testing against NORVIN specification sheets and OEM calibration standards.

NORVIN proportional valve assemblies cost INR 1.5-3 lakhs new depending on series and complexity. Synchronics repairs typically cost 30-40% of new purchase price. For a NG10 proportional directional valve, new cost is ~INR 2.2 lakhs; repair runs INR 65,000-85,000. This makes sense for production equipment out of warranty. We issue a 12-month repair warranty and provide detailed inspection reports with photos and test data to justify the investment to your CFO.

Common warning signs: slow or sluggish proportional response (spool stiction), audible chatter or oscillation, pressure spikes above setpoint, external oil weeping, or erratic readings on the proportional feedback display. If your NORVIN system exhibits any of these after routine filter change and fluid analysis, contact Synchronics for a free diagnostic evaluation. We perform response time testing, leak-rate measurement, and pressure ripple analysis to confirm whether cleaning, electronics repair, or component replacement is needed.

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.

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.

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.

Yes. If we cannot repair your NORVIN 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.
