ARA Product Lines We Repair
Our engineers are trained on the full ARA product range. Below are the major product families we service.
ARA Proportional Directional Valves
Electro-hydraulic proportional spool valves for precision flow and pressure control. Common issues include solenoid coil burnout, spool stiction, internal leakage, and proportional amplifier card failure in industrial presses and injection molding equipment.
ARA Proportional Pressure Reducing Valves
Precision pressure regulation for complex hydraulic circuits. Typical faults include pilot stage spool wear, proportional solenoid malfunction, pressure offset errors, and internal valve block cracking under cyclic load.
ARA Solenoid Cartridge Valve Systems
Modular solenoid-operated cartridge valves for integration into manifold blocks. Repair challenges include pilot solenoid core seizure, proportional coil degradation, poppet seat leakage, and electromagnetic interference affecting digital feedback.
ARA Proportional Amplifier Cards
Electronic control cards managing solenoid current, pressure feedback, and load compensation. Failure modes include capacitor degradation, power transistor burnout, microcontroller firmware corruption, and analog signal conditioning circuit failure.
ARA Integrated Pressure Control Manifolds
Multi-function pressure and flow control blocks combining proportional spools, check valves, and integrated electronics. Common repairs address internal porting erosion, proportional valve spool scratching, pressure transducer malfunction, and manifold block micro-cracking.
ARA Proportional Flow Control Valves
Electro-hydraulic flow regulation for synchronized multi-actuator systems in industrial presses and material handling. Failure points include proportional solenoid armature stiction, pressure compensator malfunction, internal spool wear, and electronic feedback transducer drift.

Common ARA Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in ARA equipment arriving at our workshop.
- ✓Proportional solenoid coil open circuit failure — Extended exposure to high ambient temperature, moisture ingress through damaged connector, or voltage surge damage in ARA proportional directional and pressure reducing valves. Indian industrial environments with high humidity and inadequate electrical protection increase failure frequency.
- ✓Internal spool stiction and sluggish proportional response — Hydraulic fluid contamination, varnish deposit accumulation, and corrosion of ARA spool rod surfaces reduce proportional response time in directional and pressure control valves. This is widespread in Indian manufacturing where fluid maintenance intervals are extended.
- ✓Pressure amplifier card malfunction and proportional offset error — Electrolytic capacitor failure in ARA proportional amplifier boards caused by thermal cycling and extended service life. Microcontroller firmware corruption or power transistor gate driver failure results in erratic pressure feedback and loss of proportional control authority.
- ✓Cartridge solenoid pilot stage blockage — Hydraulic fluid degradation and micro-particle accumulation in ARA solenoid cartridge pilot passages restrict solenoid armature movement. Common in Indian plants where fluid filtration maintenance is inconsistent, causing cartridge to remain stuck in neutral position.
- ✓Internal leakage across proportional spool seals — Prolonged cyclic loading, pressure transient spikes, and contaminated hydraulic fluid cause wear on ARA proportional spool seal rings and poppet seats. This results in gradual pressure loss and reduced system accuracy in injection molding and press applications.
- ✓Pressure transducer signal drift and feedback instability — Thermal shock exposure, electrical connector corrosion, and analog signal amplifier drift in ARA proportional amplifier cards cause erratic pressure feedback readings. Indian environmental conditions with temperature fluctuations and humidity expose transducers to accelerated degradation.

Frequently Asked Questions — ARA Repairs
Do you repair ARA equipment anywhere in India?+
Yes. Synchronics repairs the complete ARA product range — proportional directional valves, pressure reducing valves, solenoid cartridge systems, proportional amplifier cards, and integrated manifold blocks. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bangalore, and all other major cities. All repairs are performed at our certified facility in Vadodara, Gujarat.
What is the typical turnaround time for ARA proportional valve repair?+
Standard ARA proportional valve repair turnaround is 7-10 working days from receipt of equipment, including complete disassembly, precision cleaning, seal replacement, solenoid refurbishment, and pressure flow testing. For urgent requirements, Synchronics offers 48-72 hour express repair for critical injection molding and press applications affecting production schedules.
Can Synchronics repair ARA proportional amplifier cards with microcontroller firmware issues?+
Yes. Synchronics has specialized expertise in ARA proportional amplifier card diagnosis and repair. We perform microcontroller firmware reflashing to latest ARA revisions, replace degraded electrolytic capacitors with industrial-grade equivalents, repair power transistor gate driver circuits, and perform full analog signal conditioning validation. Post-repair load-based testing confirms proportional response accuracy.
How do I know if my ARA solenoid cartridge needs repair?+
Common signs include: sluggish proportional response, inability to achieve commanded pressure, solenoid coil open circuit fault codes, pilot stage not responding to electrical signal, and reduced flow accuracy. If your ARA injection molding or press system shows inconsistent proportional control, contact Synchronics for free diagnostic evaluation. We identify whether solenoid, cartridge assembly, or amplifier card requires repair.
What warranty does Synchronics provide on ARA proportional valve repairs?+
Synchronics provides 12 months comprehensive warranty on all ARA proportional valve repairs, covering parts and labor. Warranty includes proportional response accuracy, internal leakage rate, and solenoid coil integrity. If any ARA repaired component fails within warranty period due to manufacturing defect, we repair or replace at no charge. Extended warranty options are available for mission-critical hydraulic circuits.
How do I send my ARA 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 ARA 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 ARA 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 ARA 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.
