BOUYER Product Lines We Repair
Our engineers are trained on the full BOUYER product range. Below are the major product families we service.
Proportional Directional Control Valves (NG10 / CETOP-05)
Bouyer's flagship proportional spool valve series used in injection moulding machines and hydraulic presses. Common faults include proportional solenoid coil burnout, spool position feedback sensor drift, and valve spool mechanical stiction causing erratic machine movements.
Electronic Control Modules and Amplifier Cards
Integrated proportional valve control electronics featuring PWM amplification, pressure feedback monitoring, and safety interlocks. Failures typically involve output stage transistor burnout, capacitor dry-out, and software corruption in EEPROM memory.
Load Check and Pilot Stage Valve Assemblies
Pilot-operated check and load-sensing valve blocks with integrated Bouyer electronics. Common issues include pilot solenoid valve stiction, check seal degradation under high pressure cycling, and sensor signal noise from EMI in factory environments.
Proportional Pressure Relief Valve Modules
Precision pressure control valves with integrated electric proportional pilot stage for closed-loop pressure regulation in steel rolling mills and hydraulic presses. Failures include proportional magnet coil shorts, relief seat sealing surface erosion, and pressure transducer malfunction.
Integrated Valve Manifolds with Embedded Electronics
Custom sandwich-plate and cavity-ported manifolds with mounted proportional valve spools and onboard ECM cards. Repair challenges include internal leakage path diagnosis, manifold porting blockage, and interconnected electronics faults requiring full system testing.

Common BOUYER Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in BOUYER equipment arriving at our workshop.
- ✓Proportional solenoid coil burnout and coil resistance collapse — Bouyer proportional solenoid coils fail due to sustained high current draw from PWM amplifier transistor failure, incorrect coil winding resistance specification replacement, or inadequate coil cooling in high-ambient factory conditions common in Indian steel plants.
- ✓Proportional spool position sensor LVDT signal drift and loss of feedback — Bouyer LVDT transducers drift due to magnetic core creep under continuous proportional modulation, contamination ingress from failing rod seals, or amplifier bridge circuit capacitor dry-out affecting the AC carrier signal generation.
- ✓Amplifier output stage transistor short circuit and power supply collapse — Bouyer control modules fail when output transistors are exposed to solenoid coil inductive transient spikes, inadequate flywheel diodes, or gate drive circuit malfunction. High humidity in Indian monsoon climates also accelerates PCB corrosion and parasitic leakage currents.
- ✓Valve spool mechanical stiction and proportional response sluggishness — Bouyer proportional valve spools stick due to microscopic silt and rust particle accumulation in tight spool clearances (< 5 microns), seal swelling from hydraulic fluid degradation, or micro-galling of spool bore from metal-to-metal contact during high-pressure spikes.
- ✓Integrated manifold internal leakage and cross-port contamination — Bouyer sandwich-plate manifolds develop internal leaks when cavity-ported passages erode from cavitation bubble collapse, or when seal stack compression relaxes over years of thermal cycling in Indian automotive injection moulding shops operating at 85-95 degC ambient.
- ✓Software corruption and EEPROM fault codes in proportional control modules — Bouyer ECM firmware corruption occurs from power supply voltage transients during factory switchover from generator to grid, failed backup battery for non-volatile memory retention, or malware ingestion via unprotected CAN/modbus fieldbus connectors in networked Indian industrial facilities.

Frequently Asked Questions — BOUYER Repairs
Do you repair Bouyer proportional valve controllers and manifolds across India?+
Yes, Synchronics repairs the complete Bouyer proportional valve product range including directional control valves, pressure relief modules, electronic amplifier cards, and integrated manifold assemblies. We offer same-day dispatch pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bangalore, and all metro cities. Repair happens at our ISO 9001-certified facility in Vadodara, Gujarat, with full test certification.
What is Bouyer's common proportional valve fault in Indian steel plants, and how do you diagnose it?+
The most common issue is proportional solenoid coil burnout combined with LVDT feedback sensor drift in Bouyer NG10 proportional valves used on hydraulic presses and rolling mills. Synchronics diagnoses this using precision resistance measurement, hi-pot dielectric testing, and dynamic LVDT bridge nulling. We then replace the coil, recalibrate the amplifier gain, and pressure-test the valve to confirm proportional response linearity within Bouyer's 1% hysteresis specification.
Can you recalibrate and restore my Bouyer proportional valve electronics without replacing the entire module?+
Yes. Synchronics specializes in precision recalibration of Bouyer proportional control modules using calibrated function generators and oscilloscopes. We adjust PWM frequency, current limits, LVDT feedback gain, and pressure compensation curves to factory specifications. This approach saves cost versus module replacement and is suitable for most Bouyer amplifier card and ECM failures. Full documentation and calibration certificates provided.
How do you handle Bouyer manifold cavity leakage and internal seal degradation?+
Bouyer sandwich-plate manifolds are inspected using dye-penetrant testing and controlled pressure auditing to identify internal leak paths. Synchronics carefully disassembles the manifold stack, replaces failed seal rings and cavity plugs using genuine Bouyer gasket kits, and verifies cavity porting alignment under low-pressure air flow. We then perform hydrostatic pressure testing to 1.25x rated pressure and sign-off with full traceability documentation for your plant maintenance records.
What is your turnaround time for Bouyer proportional valve and amplifier repair?+
Standard turnaround is 3-5 working days for proportional valve controller repairs, and 5-7 working days for integrated manifold rebuilds, depending on complexity and parts availability. Urgent breakdown situations can be expedited to 24-48 hours for Bouyer solenoid coil and amplifier card faults. We maintain buffer stock of common Bouyer replacement coils, seals, and transistor modules at our Vadodara facility.
How do I send my BOUYER 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 BOUYER 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 BOUYER 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 BOUYER 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.
