RAVARINI Equipment We Repair — By Category
RAVARINI Product Lines We Repair
Our engineers are trained on the full RAVARINI product range. Below are the major product families we service.
Ravarini Hydraulic Power Units (HPU)
Self-contained hydraulic systems combining pump, motor, reservoir, and control electronics. Common repairs include pump cavitation, solenoid valve stiction, and electronic pressure regulator drift causing unstable load holding or erratic flow delivery.
Electronic Proportional Governors
Proportional directional control valves with integrated electronic feedback loops managing flow and pressure dynamically. Repair focus: LVDT sensor failures, proportional solenoid coil burnout, and command signal interpretation errors.
Pressure Regulation Assemblies
Modular pressure-reducing and load-sensing valve blocks with electronic pilot control. Common issues include pilot solenoid failure, spool stiction, and onboard electronics controller malfunction leading to pressure oscillation.
Flow Divider Control Systems
Flow division units managing multi-actuator synchronisation with electronic feedback. Failures typically occur in flow sensing electronics, proportional solenoid response lag, and pressure compensation drift.
Electronic Pilot Amplifier Cards
Stand-alone control modules processing 4-20mA command signals to proportional solenoid drives. Repair issues: analog input conditioning failures, PWM drive stage short-circuits, and temperature compensation drift in long-running systems.
Why Choose Synchronics for RAVARINI Repairs?
PCB-Level Expertise
We repair down to the component level — not just swap boards. Our engineers identify root causes, replace failed IGBTs, capacitors, processors, and gate drivers on RAVARINI equipment.
Fast Turnaround
Standard 7–10 working days. Express 3–5 days available for critical breakdowns. Emergency same-day/next-day service for unplanned downtime.
6-Month Warranty
Every repaired unit ships with a 6-month comprehensive warranty on parts and labour. Our repair success rate is over 94% across all brands.
All-India Service
Couriered repairs accepted from any city in India. Doorstep pickup available in Vadodara, Mumbai, Pune, Ahmedabad, Surat, Chennai, and more.
Common RAVARINI Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in RAVARINI equipment arriving at our workshop.
- ✓Proportional solenoid coil open-circuit failure — Ravarini solenoids experience insulation breakdown due to moisture ingress in humid Indian climates (especially coastal or monsoon regions) combined with thermal cycling in sugar mill and paper plant environments. Contaminated hydraulic fluid accelerates solenoid armature friction.
- ✓LVDT pressure transducer signal drift — Ravarini pressure transducers mounted in thermal-shock environments (foundries, steel mills) experience bridge amplifier offset drift and sensor calibration loss. Contaminated hydraulic media accelerates diaphragm corrosion.
- ✓Electronic governor control loop instability and hunting — Ravarini proportional governors exhibit oscillatory pressure or flow response when pilot solenoid response time degrades, feedback signal is noisy, or P/I/D tuning constants drift due to aging capacitors in controller electronics.
- ✓Pump cavitation and suction line pressure instability — Ravarini HPU inlet strainers clog in textile mills and sugar plants due to hydraulic fluid oxidation and water contamination in monsoon storage conditions. Low suction pressure triggers pump noise and reduced displacement.
- ✓Onboard electronic controller PCB failure and signal loss — Ravarini integrated control cards suffer solder joint fatigue on heavy vibrating machinery (crushing, extrusion, metal stamping) and thermal stress from ambient temperatures exceeding 50°C in enclosed electrical panels without cooling.
- ✓Solenoid valve response time degradation and leakage — Ravarini solenoid spools wear under continuous duty cycles in high-speed paper mills and textile plants, causing spool stiction, internal leakage past seals, and delayed proportional response when pilot pressure drops.

Frequently Asked Questions — RAVARINI Repairs
Do you repair Ravarini equipment anywhere in India?+
Yes. Synchronics repairs the complete Ravarini product range - hydraulic power units, proportional governors, pressure regulators, solenoid valves, and electronic control cards. We offer PAN India pickup and repair from our Vadodara facility with same-day diagnostics and 7-10 day turnaround. Regional support available through partner networks in Mumbai, Delhi, Pune, Chennai, and Hyderabad.
What is the typical turnaround time for Ravarini HPU repair at Synchronics?+
Standard Ravarini hydraulic power unit diagnosis and repair takes 10-14 business days including pump testing, solenoid recalibration, pressure valve restoration, and final commissioning test. Emergency 48-hour repairs available for critical sugar mill and steel mill shutdowns. We ship repair status updates daily and perform full load testing before return.
Can Synchronics repair Ravarini proportional solenoid valves onsite or must we send them to Vadodara?+
Complex proportional valve rebuilds require our Vadodara facility with precision hydraulic test benches and calibrated transducers. However, for on-site emergency support, Synchronics can supply rebuilt proportional solenoids with 24-hour courier delivery across India. We also conduct remote diagnostics and technical guidance via video calls for industrial customers in sugar mills and foundries.
What warranty do you provide on repaired Ravarini electronic governors and control cards?+
All Ravarini repairs carry 12 months functional warranty on repaired components and labor. Replaced parts (solenoids, transducers, capacitors, seals) carry OEM equivalent guarantees. Warranty covers material defects and workmanship but excludes damage from power surges, contaminated hydraulic fluid, or improper pilot supply pressure.
Are Ravarini replacement parts available in India, or must we import from Italy?+
Synchronics stocks common Ravarini replacement items - solenoid coils, LVDT sensors, seal kits, proportional cartridges, and electronic amplifier cards. For obsolete or long-lead components, we source directly from Ravarini's Italian facilities via established supplier relationships, typically delivering parts within 2-3 weeks. We also supply equivalent OEM-grade substitutes when original parts face extended lead times.
How do I send my RAVARINI 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 RAVARINI 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 RAVARINI 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 RAVARINI 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.
