BRONCO Product Lines We Repair
Our engineers are trained on the full BRONCO product range. Below are the major product families we service.
BRONCO Proportional Directional Control Valves (PDCV Series)
Proportional spool valves with integrated solenoid actuation for precise flow control in hydraulic circuits. Common issues include solenoid coil burnout, spool stiction, electrical connector corrosion, and loss of proportional response. Requires calibration and spool polishing.
BRONCO Pressure Relief Valve Electronics (PRV Control Module)
Pilot-operated pressure relief systems with electronic pressure regulation. Failures include proportional solenoid malfunction, pressure transducer drift, onboard amplifier faults, and electrical noise interference in fieldbus applications.
BRONCO Flow Control & Throttle Electronics
Integrated proportional flow control modules for servo-hydraulic systems. Typical faults include erratic spool positioning, amplifier thermal shutdown, transducer signal loss, and connector pin looseness due to vibration.
BRONCO Pressure Transducers & Feedback Sensors
4-20mA and 0-10V pressure transducers with ceramic sensing elements for harsh industrial environments. Common failures: diaphragm fatigue, electrical connector water ingress, amplifier IC failures, and zero/span drift over time.
BRONCO Solenoid Coil & Driver Electronics
High-power solenoid drivers for large directional valves in presses and injection moulding machines. Faults include coil insulation breakdown, driver transistor failure, EMI-induced logic errors, and connector oxidation in humid Indian plants.
BRONCO Integrated Hydraulic Control Modules
Multi-function onboard electronics combining proportional valve control, pressure monitoring, and CANbus/Profibus fieldbus. Issues arise from firmware corruption, real-time loop timing errors, power supply ripple sensitivity, and thermal management in sealed cabinets.

Common BRONCO Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in BRONCO equipment arriving at our workshop.
- ✓Solenoid coil open circuit and no proportional response — Bronco solenoid coils suffer insulation breakdown when exposed to moisture in Indian humid environments or electrical transients from nearby welding. Vibration in press machines can also cause internal wire fracture inside the coil bobbin.
- ✓Proportional spool stiction and jerky valve response — Bronco proportional valves accumulate sediment and varnish from degraded hydraulic fluid, causing spool stiction. Indian plants often operate in dusty environments; contamination ingress past seals leads to spool-to-bore friction.
- ✓Pressure transducer signal drift and zero offset error — Bronco ceramic diaphragm transducers drift due to thermal cycling in hot injection moulding facilities, or from repeated pressure spikes above rated specs. Connector corrosion in humid coastal plants adds 4-20mA signal noise.
- ✓Onboard Bronco control module resets under load or intermittent fieldbus dropout — Power supply ripple or voltage sag during heavy solenoid switching causes the microcontroller watchdog to reset. CANbus/Profibus signal loss occurs when shielded twisted pair cables are routed near three-phase mains in Indian industrial cabinets.
- ✓Electrical connector corrosion and intermittent pin contact failure — Bronco valves installed outdoors or in high-humidity manufacturing environments (textile dyeing, food processing, coastal steel mills) suffer IP54-rated connector degradation. Salt spray accelerates corrosion of tin-plated pins.
- ✓Proportional solenoid driver amplifier thermal shutdown and reduced duty cycle — Bronco MOSFET or bipolar drivers in large proportional valve modules generate excessive heat in continuous high-frequency PWM operation. Inadequate thermal interface between amplifier IC and heat sink, or blocked ventilation in sealed control cabinets.

Frequently Asked Questions — BRONCO Repairs
Do you repair Bronco equipment anywhere in India?+
Yes. Synchronics repairs the full Bronco hydraulic electronics range — proportional directional control valves, pressure relief modules, flow control systems, transducers, and integrated hydraulic control modules. We offer PAN-India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Surat, Indore, and all other major cities. Repairs are carried out at our main facility in Vadodara, Gujarat, with rapid turnaround on critical equipment.
What is the typical repair time for a Bronco proportional valve with solenoid coil failure?+
Bronco proportional valve solenoid coil replacement typically takes 3-5 working days at Synchronics. This includes coil insulation testing, solenoid replacement, spool recalibration, pilot pressure balancing, and final functional test on our pressure test rig. If spool surface damage is found during disassembly, polishing adds 1-2 days. We provide daily email updates and rush shipping options for urgent production restarts.
Can Synchronics calibrate Bronco pressure transducers to our exact process requirements?+
Yes. Synchronics performs precision two-point and multi-point zero, span, and linearity calibration of Bronco transducers using NIST-traceable pressure calibration standards and fluid. We can adjust transducer output to match your exact 0-250 bar, 0-400 bar, or custom range specifications. Certificates of calibration with measurement uncertainty are provided for quality audit compliance.
We have intermittent CANbus dropout on our Bronco hydraulic control module during high-speed injection cycles. What is the issue?+
Common cause: EMI from nearby three-phase mains, VFDs, or servo drives coupling into unshielded or poorly grounded CANbus cables in dense Indian industrial control cabinets. Synchronics identifies EMI sources, upgrades to properly shielded twisted-pair cabling with ferrite chokes at both ends, adds termination resistors, and programs watchdog logic to log fieldbus errors. We perform full-cycle functional testing to confirm stable communication under full production load.
Are Bronco proportional valve spools and solenoids available as genuine spare parts through Synchronics?+
Synchronics maintains a stock of Bronco replacement solenoid coils, spool seals, and pressure relief cartridges for emergency repairs. For larger spool assemblies and integrated valve bodies, we work directly with Bronco distributors to source OEM parts within 5-7 working days. We also offer remanufactured spools and cleaned subassemblies at lower cost for non-critical spares inventory. Lead times vary; contact our support team with your Bronco model number for exact availability.
How do I send my BRONCO 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 BRONCO 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 BRONCO 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 BRONCO 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.
