DAVCO Repair Services India

Yes. Synchronics repairs the full DAVCO product range — proportional directional control valves, load-check cartridges, proportional pressure reducers, hydraulic control modules, spool position transducers, and proportional solenoid driver amplifiers. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bangalore, and all major Indian cities. All repairs are performed at our ISO 9001 certified facility in Vadodara, Gujarat, with full traceability and DAVCO compatibility testing.

Standard DAVCO proportional valve and amplifier card repairs take 5-7 working days from receipt, including full diagnostic testing, component-level repair or replacement, functional validation on our hydraulic test bench, and quality inspection. Urgent expedited service is available for critical production shutdowns — we can prioritize repairs within 24-48 hours for emergency situations. All repairs include 12-month warranty against defects.

Yes. Synchronics specializes in rehabilitating moisture-damaged and thermally stressed DAVCO hydraulic electronics common in Indian textile mills, coastal sugar plants, and high-humidity manufacturing environments. We perform conformal coating application, connector re-sealing with IP67-rated alternatives, corrosion removal from PCB traces, and component replacement. We then validate performance under full temperature range (-10 to +60C) before return. Damaged DAVCO control modules are often fully recoverable at 40-60% lower cost than replacement.

Synchronics validates DAVCO proportional amplifier cards using a multi-stage test protocol: (1) high-voltage insulation resistance testing to confirm solenoid coil integrity, (2) PWM output waveform analysis under simulated proportional load, (3) current limiting and over-current protection response testing, (4) thermal stress at full current for 2-hour burn-in, and (5) functional proportional valve command response on a live hydraulic circuit with load feedback. Every repaired amplifier card includes a signed test report with voltage/current waveform screenshots.

Yes. Synchronics recalibrates DAVCO linear variable differential transformer (LVDT) and magnetostrictive spool position transducers across the full industrial temperature range using precision pressure/displacement standards traceable to NIST. We provide ISO 17025 compliant calibration certificates with accuracy verification at 0%, 25%, 50%, 75%, and 100% of full spool stroke. Recalibrated transducers are returned with mounting hardware and connector sealing for immediate reinstallation in DAVCO proportional valve manifolds.

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.

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.

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.

Yes. If we cannot repair your DAVCO 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.
