GORDON PIATT Repair Services India

Yes. Synchronics repairs the complete Gordon Piatt product range across India — proportional directional valves, pressure regulators, integrated automation controllers, valve driver amplifiers, and legacy analog modules. We offer PAN India door pickup from Mumbai, Delhi, Bangalore, Pune, Chennai, Hyderabad, Ahmedabad, Kolkata, and all tier-2 manufacturing hubs. All repairs are performed in our fully equipped facility in Vadodara, Gujarat, with same-day diagnostics and typically 7-10 day turnaround for complex assemblies.

Our comprehensive proportional valve repair covers complete disassembly, ultrasonic cleaning, visual spool and seal inspection, bore polishing to restore tolerances, pilot passage flushing, proportional solenoid testing and re-spooling, feedback transducer calibration, and full functional validation on customer-specific pressure and flow setpoints. We test spool response at multiple command frequencies, measure hysteresis, and confirm pressure stability over time. All repaired valves are pressure-tested, leak-tested, and documented with flow-pressure curves before shipment.

Absolutely. Synchronics specializes in legacy Gordon Piatt analog and discrete component control boards dating back to the 1990s. We repair component-level failures including electrolytic capacitor replacement, operational amplifier re-soldering, potentiometer cleaning, relay contact reconditioning, and transistor/diode substitution using modern equivalents. We maintain schematic libraries and test procedures for discontinued models. Older boards are often more cost-effective to repair than replace, and we ensure full backward compatibility with existing hydraulic circuits.

Synchronics diagnoses proportional command faults (loss of solenoid drive signal), feedback transducer errors (signal out-of-range or noise-induced oscillations), pressure relief valve failures, internal leakage codes indicating seal degradation, and proportional response delay errors suggesting spool stiction or pilot stage obstruction. For integrated controllers, we troubleshoot communication errors on CAN and serial networks, firmware corruption, analog input signal conditioning problems, and proportional output card saturation. We use Gordon Piatt-compatible test equipment and provide detailed fault diagnostics and repair records.

We conduct multi-stage validation: initial bench testing of all electrical and electronic components, functional testing under simulated operating pressures and flow rates, thermal cycling to verify stability, EMI immunity testing for environment-hardened operation, and extended soak testing under process-equivalent load cycles. All proportional valves undergo flow-pressure curve characterization to verify repeatability. Repaired equipment is delivered with test certificates, pressure curves, and responsive technical support. We offer 12-month warranty on all repairs, with rapid remote diagnostics if field issues arise.

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 GORDON PIATT 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.
