IMAL Product Lines We Repair
Our engineers are trained on the full IMAL product range. Below are the major product families we service.
IMAL Proportional Directional Valves
Hydraulic directional control valves with proportional solenoid actuation for precise flow and pressure management. Common issues include solenoid coil burnout, spool stiction, and pilot pressure loss affecting machinery responsiveness.
IMAL Pressure Reducing and Relieving Valves
Compact pilot-operated pressure control valves for system protection and load holding. Prone to cartridge seal degradation, spring fatigue, and pilot port blockage in contaminated hydraulic systems common in Indian industrial environments.
IMAL Flow Control and Throttle Valves
Precision metering valves for speed control in hydraulic cylinders and motors. Repair focus includes needle valve calibration drift, internal leakage, and erosive wear from contaminated fluid in harsh plant conditions.
IMAL Integrated Automation Controllers
Electronic controllers for multi-function hydraulic systems with CAN, Profibus, and analog I/O integration. Electronic failures include relay burnout, sensor input card faults, and firmware corruption from power surges affecting Indian industrial grids.
IMAL Servo-Proportional Manifold Systems
Integrated multi-valve manifold blocks with servo feedback for closed-loop pressure and flow control in precision applications. Common faults include manifold body micro-leakage, internal passage erosion, and electronic feedback sensor degradation.
IMAL Solenoid Actuation and Pilot Amplifier Units
High-power proportional solenoid coil assemblies and pilot pressure amplification modules for large valve control. Failures stem from moisture ingress, coil insulation breakdown, and amplifier transistor thermal stress in plants without climate control.

Common IMAL Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in IMAL equipment arriving at our workshop.
- ✓Proportional solenoid coil electrical open circuit — Moisture ingress through cable gland in humid Indian factory environments combined with thermal cycling of the coil insulation. Extended operation in high-temperature hydraulic oil (above 60 degrees C) accelerates dielectric breakdown in IMAL solenoid windings.
- ✓Proportional directional valve spool stiction and sluggish response — Degraded mineral hydraulic oil with varnish deposits coating the precision spool bore in IMAL valves, compounded by contaminated fluid bypassing filtration in older Indian manufacturing plants. Corrosive water content from poor hydraulic maintenance accelerates micro-pitting.
- ✓Pilot pressure loss and reduced valve response — Blockage of pilot port passages in IMAL proportional valve body due to particulate contamination or degraded seal material flaking. Common in plants where hydraulic fluid change intervals exceed OEM recommendations, particularly in high-ambient Indian facilities.
- ✓Internal leakage and loss of load-holding pressure in relief valves — Wear and erosion of the pilot-operated cartridge cone and seat in IMAL pressure reducing valves due to prolonged operation with unfiltered bypass flow or contaminated pilot signal fluid in India's variable-quality hydraulic environments.
- ✓Electronic automation controller relay chattering and rapid switching — Degraded relay contact surfaces in IMAL IAC controllers from arc erosion during inductive solenoid valve switching, worsened by inadequate transient suppression in plants with aging electrical distribution systems prone to voltage spikes.
- ✓Manifold block internal passage micro-leakage and loss of system pressure — Fatigue cracking or erosive wear of internal porting surfaces in IMAL servo-proportional manifold bodies after extended high-pressure operation in heavy machinery, particularly when pilot relief settings have been tampered with or exceeded during troubleshooting.

Frequently Asked Questions — IMAL Repairs
Do you repair IMAL equipment anywhere in India?+
Yes. Synchronics repairs the complete IMAL product range including proportional directional valves, relief cartridges, automation controllers, and servo-proportional manifolds. We offer PAN-India door-to-door pickup and delivery from major industrial hubs: Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Surat, and all other cities. All repairs are performed at our Vadodara, Gujarat facility with 180+ engineers and full diagnostic equipment for IMAL systems.
What is the typical turnaround time for IMAL proportional valve repair?+
Standard IMAL valve repairs including solenoid replacement, spool cleaning, and seal kits average 7-10 working days from receipt. Express diagnostics are completed within 24 hours. Manifold body repairs requiring specialized welding or epoxy sealing may extend to 14-21 days. We provide daily email updates and expedite logistics for critical production stoppages affecting Indian manufacturers.
Can you rebuild IMAL pilot-operated relief cartridges to OEM specifications?+
Yes. Synchronics stocks genuine IMAL cartridge kits and performs complete rebuilds including cone and seat replacement, pilot drain calibration, and bench-pressure testing to within 5 bar of original setpoint. We use only OEM-equivalent seals and springs to ensure cartridge life and stability. Rebuilt cartridges carry a 12-month functional warranty against leakage.
Do you repair IMAL automation controllers with Profibus or CAN networking?+
Yes. Our engineers service IMAL IAC series controllers including firmware diagnostics, relay and power transistor replacement, and sensor input card rework. We perform network simulation testing for Profibus and CAN integration before return. Control logic parameter backups are created during repair to streamline commissioning in your Indian plant without reprogramming.
What causes IMAL proportional valve solenoid coil failure so frequently in Indian plants?+
IMAL solenoid coils are sensitive to moisture ingress and thermal stress. In India's high-humidity coastal regions (Mumbai, Chennai) and dusty inland areas (Pune, Ahmedabad), cable gland seals degrade allowing condensation. High ambient temperatures in summer months (45-50 degrees C) combined with hot hydraulic oil push coil insulation beyond rating, causing breakdown. Synchronics recommends annual solenoid megohm testing and climate-controlled storage for replacement units. We potted replacement coils with epoxy for superior moisture resistance.
How do I send my IMAL 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 IMAL 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 IMAL 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 IMAL 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.
