AAK CORPORATION Product Lines We Repair
Our engineers are trained on the full AAK CORPORATION product range. Below are the major product families we service.
AAK Directional Control Valves (4/3, 4/2 Spool Valves)
Manual, solenoid, and proportional directional control valves for excavators, wheel loaders, and industrial presses. Common faults include solenoid coil burnout, spool stiction from contamination, and proportional electronics failure in pilot-operated models.
AAK Pressure Relief and Pilot-Operated Valves
Load-sensing and pressure relief valves for circuit protection in mobile and stationary hydraulic systems. Typical issues include cracking pressure drift, internal seal wear, and cartridge valve blockage from particle contamination.
AAK Proportional Solenoid Control Systems
Proportional directional and pressure control valves with integrated electronics for precise flow and pressure modulation. Faults include solenoid hysteresis issues, amplifier card degradation, and proportional spool response lag from silt buildup.
AAK Hydraulic Accumulators and Bladder Packs
Diaphragm and bladder accumulators for energy storage, shock absorption, and pulsation damping in construction and industrial machinery. Common failures include bladder rupture, precharge loss, and shell corrosion.
AAK Filtration and Tank Mounted Systems
High-pressure and tank-top filtration units protecting hydraulic systems from particle contamination. Repair needs include element clogging, bypass valve wear, and differential pressure indicator stuck conditions.

Common AAK CORPORATION Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in AAK CORPORATION equipment arriving at our workshop.
- ✓Solenoid coil burnout in directional control valves — AAK solenoid coils fail due to sustained current draw from dirty proportional electronics or internal coil insulation breakdown from thermal cycling in outdoor-mounted agricultural and construction equipment exposed to Indian heat and humidity.
- ✓Spool stiction and sluggish response in NG10/NG16 valves — Indian construction and quarry equipment operating in dusty environments suffer spool stiction when fine particles accumulate in spool lands, reducing flow response time. Water ingress from monsoon humidity causes microstructural corrosion on spool surfaces.
- ✓Proportional electronics amplifier card failure and erratic modulation — AAK PAOP and PRDP proportional solenoid systems experience amplifier failures from transient voltage spikes on Indian plant electrical systems lacking proper surge suppression, plus capacitor aging in high-humidity industrial environments.
- ✓Pressure relief valve cracking pressure drift and instability — AAK pilot-operated and direct-acting relief valves drift cracking pressure due to internal seat wear from high cycle-count equipment (stone crushers, extruders), vent port blockage from fluid oxidation, and contamination-induced cartridge spool hang-up.
- ✓Bladder accumulator rupture and precharge loss — AAK bladder accumulators in Indian mobile equipment fail from excessive charge/discharge cycling (excavators working 14-hour days), corrosion perforation from external salt spray in coastal states, and incorrect precharge pressures during commissioning.
- ✓Manifold port blockage and pilot stage flow starvation — Custom AAK manifold assemblies used in Indian plastic extrusion and metal forming equipment suffer internal port blockage from oxidized fluid residue buildup, filter bypass events introducing silt, and hardened varnish from thermal degradation at high cycle rates.

Frequently Asked Questions — AAK CORPORATION Repairs
Do you repair AAK Corporation equipment anywhere in India?+
Yes. Synchronics repairs the full AAK Corporation product range — directional control valves, pressure relief valves, proportional solenoid systems, accumulators, and manifold assemblies. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bangalore, and all other cities. All equipment is shipped to our factory in Vadodara, Gujarat for diagnostic testing, repair, and full pressure validation before return.
What is the typical turnaround time for AAK proportional solenoid valve repair?+
Standard AAK proportional solenoid repairs (coil replacement, amplifier card repair, spool cleaning, calibration) require 7-10 working days including component sourcing, bench diagnostics, pressure testing, and thermal cycle validation. Urgent repairs on in-stock components can be expedited to 3-5 days. We provide daily status updates and accept equipment via FedEx or DHL nationwide.
Can Synchronics repair AAK directional control valves with custom manifold blocks?+
Yes. Synchronics has extensive experience with custom AAK valve manifold assemblies mounted on Indian extrusion, forging, and printing press equipment. We disassemble, ultrasonically clean internal cavities, replace all sealing elements, and perform full flow and pressure testing of integrated LS and pilot stage circuits. We maintain factory manifold cavity drawings and CAD models for complex custom builds.
What warranty do you provide on AAK Corporation repairs?+
Synchronics provides 12 months warranty on all AAK Corporation repairs covering parts and labor, provided equipment is operated within rated pressures and temperatures per AAK datasheets. Warranty covers proportional valve response characteristics, relief valve cracking pressure within +/- 2 percent of original setting, and accumulator bladder integrity. Damage from contaminated fluid or electrical transient spikes is diagnosed and quoted separately.
Do you stock AAK replacement components like solenoid coils and seal kits?+
Synchronics maintains genuine AAK replacement inventory including directional valve solenoid coils (12V and 24V DC), proportional spool seal kits, accumulator bladder packs, amplifier cards, and relief valve cartridge assemblies. Lead times on non-stock items are typically 10-14 days from AAK Swedish distribution. We can often repair using equivalent cross-compatible components approved for Indian industrial applications when genuine stock is unavailable.
How do I send my AAK CORPORATION 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 AAK CORPORATION 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 AAK CORPORATION 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 AAK CORPORATION 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.
