ASAHI Product Lines We Repair
Our engineers are trained on the full ASAHI product range. Below are the major product families we service.
ASAHI Solenoid Valves (2/2, 3/2, 4/3 Way)
Direct-acting and pilot-operated solenoid valves used in pneumatic and hydraulic control circuits. Common issues include coil burnout, spool stiction, seal degradation, and electromagnetic chatter causing intermittent operation in chemical dosing and process automation systems.
ASAHI Pressure Transducers and Switches
Electronic pressure monitoring devices for compressed air, hydraulic, and fluid systems. Failures include sensor drift, zero-point offset, connector corrosion in humid factory environments, and signal loss due to harsh industrial conditions.
ASAHI Flow Meters and Instrumentation
Electromagnetic and turbine flow meters for liquid and gas measurement in process control loops. Repair challenges include electrode fouling in conductive liquids, turbine bearing wear, and PCB corrosion in high-humidity environments.
ASAHI Pneumatic Control Modules
Integrated logic controllers and pneumatic sequencers for automated production lines. Typical faults include relay failure, timing module degradation, and air leakage in pilot circuits affecting cycle accuracy.
ASAHI Manifold Block Assemblies
Integrated cavity-block systems combining multiple valve functions for compact automation. Repair involves internal porting restoration, spool replacement, and cavity re-machining for worn passages and leakage paths.
ASAHI Proportional Valve Electronics
Motion control amplifiers and proportional control cards for analog and PWM-based valve command. Common failures include spool positioning signal loss, ramp-up instability, and feedback circuit board failures from thermal stress.

Common ASAHI Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in ASAHI equipment arriving at our workshop.
- ✓ASAHI solenoid coil burnout and winding failure — Continuous energisation without deactivation cycles, moisture ingress through cable glands in humid Indian factory climates, or voltage surge from unfiltered power supplies common in older Indian installations. Coil insulation breaks down, causing short-circuit and thermal damage.
- ✓ASAHI pressure transducer zero-point drift and nonlinearity — Thermal cycling in outdoor process tanks and uncontrolled factory floor environments cause electronic component drift. Calibration shift occurs due to aging capacitors in signal conditioning circuits and diaphragm material fatigue under cyclic load.
- ✓Flow meter electrode fouling and conductivity sensor blockage — Magnetic flow meters measuring conductive process liquids accumulate mineral deposits and biological film on electrodes. In Indian chemical plants, high-TSS water and chemical residues form insulating layers reducing signal strength and causing zero-flow errors.
- ✓ASAHI proportional valve spool stiction and sluggish response — Contaminated hydraulic or pneumatic systems introduce micro-particles that accumulate in spool clearances. In Indian textile mills and steel plants with dusty environments, air bypass filters become clogged, allowing abrasive particles into solenoid valve cavities.
- ✓Manifold block internal leakage and cross-port contamination — Spool wear, cavity corrosion, and damaged seals in sandwich-stack manifolds allow internal fluid bypass. Extended operation without preventive maintenance in Indian sugar mills and food processing plants accelerates cavity erosion and porting damage.
- ✓ASAHI control module relay chatter and intermittent output logic — Electromagnetic relay contacts degrade due to arcing and pitting in high-switching-frequency applications. Vibration in industrial automation lines, inadequate snubber circuits, and poor power supply filtering cause contact bounce and false switching.

Frequently Asked Questions — ASAHI Repairs
Do you repair ASAHI equipment anywhere in India?+
Yes. Synchronics repairs the full ASAHI product range - solenoid valves, pressure transducers, flow meters, proportional valve electronics, and control modules. We offer PAN India door-to-door pickup from all major cities including Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Kolkata, and smaller industrial towns. All work is done at our ISO-accredited facility in Vadodara, Gujarat with 2-7 day turnaround depending on fault complexity.
What is the typical repair cost for ASAHI solenoid valve coil replacement?+
ASAHI solenoid valve coil rewind typically costs INR 1,800-3,500 depending on coil size and insulation class. Complete solenoid assembly replacement with plunger and springs ranges INR 4,500-8,000. We always provide free diagnostic testing and a written repair quote before proceeding. If your valve is beyond economical repair, we advise replacement with compatible OEM or equivalent parts.
How do I know if my ASAHI pressure transducer needs recalibration?+
If your 4-20mA output deviates more than ±2% from expected value at known pressure points, recalibration is needed. Synchronics uses precision hydraulic test rigs to recalibrate ASAHI transducers across full operating range with NIST-traceable standards. We provide calibration certificates and recommend annual recalibration for critical process measurement applications in pharmaceutical and food plants.
Can Synchronics repair ASAHI manifold blocks with internal cavity damage?+
Yes. Synchronics performs precision cavity re-machining for worn ASAHI manifold blocks, restoring internal porting accuracy to within 0.05mm. For severe corrosion or deep scoring, we can manufacture replacement cavity inserts or recommend complete block replacement if economical. We pressure-test all manifolds to 1.5x rated pressure and certify leak-rate before return to your production line.
What warranty do you offer on ASAHI repairs?+
All ASAHI repairs carry a 12-month functional warranty covering parts and labour. If a repaired component fails within warranty due to our workmanship, we repair or replace it free of charge. We also offer optional extended care plans for high-criticality solenoid valves and transducers used in continuous-process industries like pharmaceuticals and refineries.
How do I send my ASAHI 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 ASAHI 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 ASAHI 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 ASAHI 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.
